Abstract. The article discusses the development of production technology of the foam-cement composite with the use of the secondary cellulosic fibers. Results of the study of the structure and properties of the foam-cement composite as well as the process of extracting the cellulose fibers from a sheet of paper are presented. The basic physical- mechanical and physical-chemical processes occurring during the extraction of cellulose fibers are analyzed. The mechanism of destruction of cellular composite materials under the influence of external mechanical impacts is considered. The results of experimental studies give a wide overview of the properties of the composite foam cement, possible changes and new formations in the deep layers of the porous material, ensuring higher construction and operating characteristics of the foam cement composite. Experimental studies were performed with the use of standard tools and measurement methods, as well as a complex of up-to-date physical-chemical methods of analyzing. A casual relationship between the concentration of cellulose fiber and the compressive strength of foam-cement composite has been revealed. Critical concentration of the cellulose fiber relative to the weight of cement has been established. The structural properties of products of cement hydration in the contact zone between a fiber and cement matrix are described. Positive influence of the presence of cellulose fibers in the structure of cement matrix is substantiated.
Key words: foam-cement composite, cellulose fiber, secondary cellulose fiber, opening of sheet of paper, matrix, compressive strength, cement matrix. - REFERENCES

Abstract. For many centuries the wall ceramics is the basis of the building industry when constructing various buildings and premises. Many historical monuments of architecture built of brick have undergone testing time and have proved the reliability of ceramic brick as a construction material under severe climatic conditions of operation. Today, for constructing unique objects in Yakutsk, the front brick imported from outside of the Republic is used despite the fact that the Republic Sakha (Yakutia) has sufficient land and mineral raw material resources for solving this problem. The most perspective in respect of development and production organization of ceramic bricks is the Sannikovsky field of clay raw materials. The need to develop an effective, modifying additive and optimum composition of furnace charge for manufacturing high-quality ceramic front bricks is substantiated. The introduction of the ceramic mass of finely ground cullet promotes, at the high temperature of burning, the increase in a glass phase which significantly reduces the open porosity of a product and increase the durability limit in case of compression and doesn't form salt efflorescence. By results of researches the composition of furnace charge for production of a ceramic front brick with a ground cullet is optimized.
Key words: ceramic brick, front brick, architecture, cullet, zeolite-hongurin, salt efflorescence. - REFERENCES

Abstract. Results of the experimental study on the preliminary assessment of the serviceability of products made of glass and basalt plastics under conditions of the cold climate in the absence of the direct impact of sunlight are presented. The influence of low temperatures and the exposition in the cold climate on the mechanical properties of unidirectional glass- and basalt plastic rods for construction purposes was studied during 5 years. The mechanical properties of products were determined by the buckling method under conditions of the pin-edge fixing of samples at temperatures 20 °C and -60 °C. Properties of production prototypes of glass-plastic rods of two types on the basis of polyester and epoxy binders, and basalt-plastic rods on the basis of an epoxy binder were studied. The temperature dependence of deformation and strength characteristics due to the specific properties of reinforcing fibers has been revealed. Results of the study show the significant increase (up to 20%) in the deformation-strength properties of composite rods at low temperatures and high climatic stability of products. It is experimentally established that the modules of elasticity at buckling of rods of basalt- and glass reinforcement within the limits of the valid interval remain constant at test temperatures.

Abstract. The use of wood as a structural material assumes the availability of information about its physical-mechanical properties which, in many respects, are determined by its macro-structural configuration. Among the advantages of wood are easy treatment, relatively high strength, and low specific weight. But the wood has a series of disadvantages such as flaws in the wood, low flame resistance and biostability etc. which can be removed at the stage of the technological processing (drying, preservative treatment). In addition, some features of timber, such as the anisotropy of the structure, variability of physical and mechanical properties along the radius and height of the tree trunk, require special considerations. But in the practice of manufacture of timber building structures and products, allowable values of the density distribution and macrostructure are not regulated. Issues of the influence of these parameters on mechanical properties are considered on the example of dahurian larch wood. The algorithm of forecasting physical-mechanical characteristics of the wood on the basis of its density determination has been developed. The analysis of the full factorial experiment for assessment of the influence of macrostructure features and density of the wood on mechanical parameters has been made.

Abstract. An actual issue of the building material science is increasing the water resistant of gypsum binders and materials on their basis as, at the relatively low cost, they are environmentally friendly and flame-resistant. The possibility of using the additive, which is obtained by means of mechanical-chemical activation of finely-ground zeolite-containing rocks and dibutyl phthalate plasticizer, is considered. The optimal composition of the zeolite- containing additive is determined and its influence on the physical-mechanical properties of the gypsum stone is studied by the method of mathematical planning of the experiment. The influence of the additive on the setting time of the gypsum binder, the coefficient of gypsum stone softening and its micro-structure has been established. On the basis of results of the study conducted, it is proposed to use zeolite-containing additives as nano-modifiers for heavy concretes and mortars with cement binders as an additive in the course of finishing works in premises with high relative air humidity.

Abstract. At present, the development of innovative building materials from local raw materials with the use of industrial waste becomes increasingly relevant. The present state of production and use of wood concrete and peculiarities of its manufacturing technology are analyzed. The use of a composite binder on the basis of gypsum with the introduction of a hydraulic additive consisting of Portland cement and zeolite-containing rock is substantiated. For conducting the study, the method of mathematical planning of experiment has been used. Multifactor second-order polynomial models make it possible to solve most of engineering problems in material science and technology. The factors influencing the strength of wood concrete on the basis of gypsum-cement-zeolite binder are considered. The basic physical-mechanical properties of the optimized composition are determined; the structure of relations arising between the organic filler and different binding substances in the wood concrete are studied with the help of the scanning probe microscope "NtegraPrima" NTNDT.
Key words: wood concrete, wood composite, gypsum-cement-zeolite binder, cement poisons, waste of woodworking enterprises. - REFERENCES

Abstract. During the operation of concrete structures under conditions of aggressive environments, there is a decrease in their strength and durability which leads to the growth of deformations and, as a result, to their deterioration. The method of study of concrete structure density by determining its permeability for chloride ions according to the standard ASTM C1202-97 (USA) based on measuring the amount of electric charges passing through concrete samples is considered. This experimental method is quite simple, its results have high accuracy and reflect the true nature of the structure density of reinforced concrete structures operating under the ground, in water and in other aggressive environments. Results of the study conducted show that high-quality fine concrete has lower chloride permeability and, consequently, more dense structure than conventional fine unplasticized concrete. The use of high-quality fine concretes with a modified structure for construction of underground structures facilitates the increase in corrosion resistance and improvement in the durability of reinforced concrete structures.
Key words: permeability of chloride ions, high-quality fine concrete, density of concrete structure, corrosion resistance of concrete, electric charge. - REFERENCES

Abstract. On the basis of standard statistical methods, an analysis of the main indicators of construction is presented. The database includes modern and Soviet statistics. At present, health care and education are the priorities in the current investment policy of the Republic of Sakha (Yakutia). But insufficient high volumes of investments don't make it possible to reduce the deficit of public services facilities in cities and district centers and replace the actively outgoing, worn-out stock in rural settlements. It is necessary to revise the principles of investment planning, take into account migration and demographic processes more fully, proceed to a new system of standards of provision with the social infrastructure with due regard for the regional specificity. The years of reforms were accompanied by painful but necessary structural changes. The building materials industry of the republic is gradually moving to the production of up-to-date products. The productivity significantly increased. The real estate market and mortgage lending are actively developing that makes it possible to significantly increase the volumes of housing construction including the individual construction. However, the transition to a market model has predetermined the appearance of cyclicality, which significantly affects the dynamics of the sector.
Key words: construction economics, gross regional product (GRP), structural changes, social infrastructure, improvement of housing stock, commissioning of buildings. - REFERENCES

Abstract. As a result of surveying of buildings and structures in three permafrost areas of Yakutia, main reasons for reducing the bearing capacity of bases and foundations have been revealed. When using them according to the 1st principle, the reduction in bearing capacity of permafrost soils of the base occurs as a result of malfunction of ventilated undergrounds, partial thawing of soil due to the warmth of water leaking from engineering networks, improperly performed repair works and landscaping, creation of conditions for intensification of frost heaving forces due to the hydration of the soil around foundations. The main reasons of surveyed collapses in Ust-Nera and Yakutsk were permanent hydration of concrete foundations, low quality of the concrete, reinforcement of piles was constructed not according to the requirements, lower level of foundation soils relatively with the level of surrounding territory. Surveys of buildings and structures, exploited according to the 2nd principle, show that all objects have uneven sedimentary deformations of the foundations. Deformations occurred due to the reduction in bearing capacity as a result of permafrost thawing. Despite the toughening of the requirements to the design of foundations, problems associated with the reduction of bearing capacity of foundation soils exist today at the objects constructed in recent years. The process of piles installation massively used nowadays in the capital construction is very expensive and needs too long time. The analysis of literature and preliminary results of our experiments show that the use of ribs on the side surface of piles can significantly increase the bearing capacity of foundation soils.

Abstract. The article presents the results of studies of friction pile models, carried out in the underground laboratory of the Permafrost Institute named after P. I. Melnikov of the SB RAS during the past two years; ways to increase their bearing capacity by improving the strength of pile adfreezing with interstitial water are considered. The strength of the pile adfreezing is expected to increase through the use of ribbed piles and by selecting the optimal composition of interstitial water for filling the borehole. Tests of ribbed pile models with different rib pitches in sandy soils and a similar smooth pile show that a decrease шт the rib pitches leads to the increase in bearing capacity of piles. Thus, the bearing capacity of the side surface of the ribbed pile with the rib pitch of 1 cm by 2.7 times greater than the side surface bearing capacity of the similar smooth pile. The study of different backfill solutions for filling of boreholes of driven cast-in-situ piles including the degree of strength gain of cement-sand solution under conditions of permafrost soils and and the study of the freezing point of backfills have been conducted.
Key words: friction piles, ribbed piles, permafrost soil, bearing capacity, brand strength, freezing temperature. - REFERENCES

Abstract. Features of the construction under conditions of Extreme North are considered. On the territory of the Republic of Sakha (Yakutia) predominates sharply continental climate with temperature differential amplitude of 100 °C and long harsh winter, the duration of the heating period is about 9-12 months. Because of difficult climatic features, improving the efficiency of operation of systems providing the comfort microclimate in the premises is the most relevance for solving problems of creation of optimal conditions for construction and operation of various engineering facilities and buildings. A method for preservation of the soil thermal regime at anthropogenic changes due to the human impact on the permafrost is presented. A conceptual complex model of improving the operating efficiency of recuperation systems under conditions of the Far North is proposed. Engineering methodology for calculation of heat flows of soil and the pipeline laid in the depth of soil has been developed. The presented technique of engineering calculation of the thermal regime change depending on parameters of external air will make it possible to efficiently use the energy of the cold contained in soils for heating of external air and the energy of cold air for preservation of frozen soil, thereby reducing heat energy costs.
Key words: thermal regime, extreme continental climate, permafrost soils, cooling pipe, cooling effect, operational period, recuperation system, air temperature dynamics. - REFERENCES

Abstract. Since the 2000s the pace of housing construction in the Far North increased considerably. The volume of the individual building is a half of the total volume. Geographical and territorial peculiarities of the Far North and surrounding areas involve mostly the use of autonomous systems of engineering maintenance of buildings. The quality of life in extreme conditions depends on the efficiency and reliability of these systems. The article presents the results of the implementation and operation of the modern self-contained heating and water supply systems on the territory of Yakutia. The authors analyze the operation of autonomous solid fuel fired boilers of different manufacturers on local fuel. A pilot project of complex engineering preparation of residential buildings in the Arctic areas that makes it possible to organize individual systems of heat, water supply, and water disposal systems in hard to reach places is considered.
Key words: autonomous sources of heat supply, solid fuel boilers of long burning, engineering accomplishment, design coefficient of efficiency, full-scale survey, decentralized areas at the North. - REFERENCES

Abstract. The article considers modern automated systems of personnel management which are intended for optimizing the work of the management and personnel of HR departments of the enterprises and also play a large role in increase in productivity of their work. It is emphasized that the use of automation equipment in design when scheduling the work with personnel makes it possible to take into account features of the construction sphere, to reduce production costs and increase the quality of labor. At present, this can be realized with the help of virtual forms of labor organization. It is noted that many companies of the construction industry, for the purpose of ensuring the flexibility and to avoid various movements, form virtual teams in which employees can be where they are comfortable. In some cases, several such teams, which offices carry out the activity in a virtual manner, can be located in various cities, regions, and even countries. The main difficulties and problems in virtual teams are designated. Recommendations concerning the solution of communication problems and improvement in the work of virtual groups of designers are made for the heads.

Abstract. The article analyzes the interaction of participants of an investment-construction project on the basis of powers and functions of its parties. It is noted that the efficiency of the investment project can be characterized by integral indicators of economic efficiency, which take into account results and costs of the project. Classification of the investment projects on the basis of a number of signs is proposed. The investment project is presented systematically that makes it possible to regulate the interaction of participants of the project through risk management. This is realized at all phases of the project life cycle with the use of monitoring and necessary correcting impacts on the mechanism of interaction among the project participants. The life cycle of the investment project consists of a series of successive phases. For more effective control over the development of the investment project, each phase can be divided into smaller components (phases and stages), each of which has its own objectives and implementation mechanisms. To implement the investment project, a clear list of its participants (subjects) with the distribution of roles and responsibilities among them is provided. Characteristics of subjects of investment activities are presented.

Abstract. It is proposed to strengthen the existing contract systems in construction with concession schemes which should contain the concept, basic requirements, and construction stages as well as conditions for their implementation. An experience in the nodal design and construction of industrial objects with the wide use of large-block assembling of coverings is an efficient alternative to the development of concession schemes. An experience in the construction of production buildings of machine industry is presented. In particular, an industrial complex consisting of sub-complexes, such as an industrial site, communal zone, base of building industry, units of thermal power station etc., is considered. Every sub-complex is divided into units and plots which are indicated on the master plans of sub-complexes. The composition of a start-up complex should provide the organization of technologically substantiated execution of works with the purpose of achieving, in short terms, the technical readiness for automated testing and check-out of technological lines, offices, and plants. The use of the nodal method fits well with large-block assembling of coverings with the use of conveyor lines for the assembly of structures. Introduction of the concession schemes in the contract schemes significantly increases the responsibility of building organizations and will be an important motivation for introducing innovations.
Key words: industrial construction, concession scheme, contract system, nodal method, large-block assembling, start-up complex. - REFERENCES

Abstract. The concept of integrated automated control system (ACS) for a tower concrete batching plant, which is a set of hardware maintenance, information, mathematical and software for management of technological objects of the concrete batching plant is proposed in the article. The system is scalable and can include a variety of local ACS of process of concrete mixes preparation, storage of inert materials and cement, targeted distribution of concrete, traffic control service, laboratory, hydrothermal treatment, weight service, subsystems of access control, personnel management jobs. In accordance with the proposed concept, the complex automated system should provide the optimum level of automation of the collection and processing of information for generating control signals and transmitting them without loss and distortion to the actuators in order to achieve the most efficient operation of the concrete plant.
