Problems of cement quality for factory production of building materials and structures, which include a high variability of indicators of their properties, low value of specific surface area, understated setting times, are characterized. According to the data on acceptance sampling, laboratories of the reinforced concrete products, factories of the city of Voronezh during the year made the statistical analysis of cement quality of different manufacturers on the basis of which the level of criterial cement properties for factory production was authentic assessed and compared. On the basis of the analysis of requirements of standard GOST P 50779.53–98 “Statistical methods. Acceptance sampling by variables for normal distribution. Part I. Known standard deviation” and GOST P ISO 12491–2011 “Building materials and components. Statistical methods for quality control” for the statistical method of cement quality control, complex quantitative criteria of cement quality assessment, which include the performance of regulatory level of non-conformities and quality reserves, are substantiated. Values of these criteria are calculated on the example of cement strength of different manufacturers and compared with the statistical analysis results. It is shown, that these criteria are objective, with statistical reliable characteristics of cement quality and can be proposed for enterprise-consumers as a criterion for selecting cement suppliers.

A design block of large-panel housing construction (LPHC) is considered. It is proposed to use a universal large-panel housing construction system with a narrow step as a basic system for LPHC plants. The system has multi-variant lay-outs of apartments with a diverse combination in the basic design of the block-section as well as a modular design principle of new block-sections on the basis of the existing, the mechanism of transfer of the basic block-section with a narrow step to a wide step in variant without preliminary pre-stressing. The advantage of its use in the planned Moscow program of housing renovation and resettlement from emergency five-story houses is shown. The possibility to reduce the costs when constructing including due to the use of gypsum partitions as well as the possibility to increase the capacity of the plant due to increasing the number of housing square meters are presented.

It is shown that the Russian technology of a precast-monolithic frame proposed by GC “Rekon-SMK” makes it possible to provide internal and foreign markets with qualitative, affordable and energy efficient building materials of Russian production, reduce the dependence on foreign technologies, equipment, and components. It is also shown that the efficiency of the project is determined not so much by the payback indicators as the number of constructed residential and public buildings. It is necessary to consider the possibility of changing the purpose of the object in the future. Actual data for determining the optimal capacity of a plant-mini DSK are presented. Reinforced concrete products supply to other regions can be up to 90% of the cost of products due to increasing transportation costs that makes manufacture of building materials unprofitable.

Analysis of frameless large panel buildings implies account of flexible connections between walls and slabs at places of their intersection (joints). Generally, in 3D design models of such type, a flexible connection is simulated with discrete connections of finite rigidity. The rigidity of discrete connections is determined according to the type of joint and its design features. Simulation of discrete constraints is rather a time-consuming procedure. So, if the process of their generation is automated, it will simplify the work of design engineer. LIRA-SAPR 2017 introduces the special tool for effective simulation and analysis of joints in large panel buildings; the tool is called ‘Joint’. There is a special class of information objects – joint of panels. This class enables the user to considerably simplify and automate the simulation of large panel buildings, then triangulate and obtain the finite element model. Fundamental principles of work with the ‘Joint’ tool are considered.

The analysis of the results of static and dynamic tests of reinforced concrete three-layer wall panel with flexible connections of glass-fiber reinforcement is made. As a result of static tests of panels’ layers for shear, the value of the shear stiffness coefficient of connections and the ultimate value of shearing force for the panel are established. During the process of dynamic tests of three-layer panels on the two-component vibro-platform have been simulated loads on the structure corresponding to the dynamic impacts at earthquakes of 7–9 point intensity according to the MSK-64 scale. During the test process, the frequency spectrum of impacts changed within the 1–10 Hz range at accelerations of the vibro-platform of 0.3–19 m/s². The character of behavior of a face layer relative to the bearing (self-bearing) layer of the panel under the action of dynamic load, parallel and perpendicular to the plane of panels is analyzed.

It is shown that the existing designs of large-panel houses practically don’t meet the new standards of comfort in the light of the realization of a large-scale program of housing stock renovation. The most important indicator determining the housing comfort, according to the international practice, is availability of a common room over 30 m² in the flat (in developed countries of Europe and America it can reach 100 m²), as well as bedrooms in an amount equal to the number of family members. Various options of development of the urban square are analyzed and it is concluded that the residential quarter, “carpet”, development of average height of 5–7 stories is the most efficient from the point of view of development density, ergonomic and video-ecology. The architectural and town-planning system of panel-frame houses developed by TSNIIEP zhilishcha makes it possible to provide the high speed of construction, relatively low cost, high quality of housing and its further variability for operation life up to 100 years. For wide introduction of this system there is a high-tech base of industrial housing construction. The transition to the construction of standard housing of mid-rise quarter development according to the frame-panel housing construction technology opens the perspective for the construction of comfortable housing of a new generation oriented to the creation of a humanistic society.

The developed electric pulse device (EPU) has the uniqueness and novelty in the technical solution for the use when installing bored-injection piles (piles-ERT). The EPU device makes it possible to produce piles-ERT with increased bearing capacity. Due to the presence of a high-energy capacitive accumulator with a switch that is connected to the discharger of the radiator of accumulated energy, the EPU is an original electro-technical structure. It is a unique high-performance aggregate for the installation of piles of increased bearing capacity, as well as for cementation of bases. The device has no analogues abroad. It is found wide application in geotechnical construction when erecting piles-ERT in pile fields, fencing of pits, cementation of bases, etc.

According to the requirement of CR (Construction Rules) 14.13330.2014 “Construction in Seismic Regions” (actualized SNiP II-7-81* “Construction in Seismic Regions”) (with Change №1) the main task for builders of Volgograd Oblast is erection of buildings of the raised responsibility for preservation of life and health of people at the earth-quake. However, provisions of some standard documents of the Russian Federation of a building content allow them not to do so. The article substantiates that earthquakes within the territory of Volgograd Oblast can be at any time and with much higher intensity in comparison with the standard intensity on the scale ОSR-2015 (General Seismic Zoning of the Territory of the Russian Federation). The management of Volgograd Oblast is proposed to introduce immediately the provision about probability of earthquake within the territory of the oblast in the regional law of Volgograd Oblast № 1779-ОD of 21 November, 2008 “On protection of the population and the territory of Volgograd Oblast against emergency situations of natural and anthropogenic nature”, to conduct scientific work on determining tectonic faults on territories of settlements for correction of seismic hazard.

Results of the study, on basis of which, strength and deformation characteristic of masonry were established by two methods are presented: by testing the ceramic brick, stone, and masonry mortar according to standard methods and fragments of the masonry of external walls under the static loading. The external walls of the 12-storey residential building were made of ceramic facing bricks and hollow ceramic stones. The results obtained made it possible to evaluate the masonry strength under compression and to establish the real reserve of bearing capacity of external load-bearing walls of a residential building.
