Improving the effectiveness of the bezobzhigovogo wall brick compression molding is achieved by using as a placeholder-Tripoli. Application of Tripoli helps improve brick group Thermo-technical characteristics of ineffective to conditionally effective. Provided with high marks on brick durability. A large amount of water absorption by weight and low coefficient of softening indicate low water resistance bricks. Bezobzhigovyj wall brick compression molding of the Tripoli-based can be regarded only as a private, secure personal brick or other waterproof material.

Modern programmatic complexes, supporting BIM technologies, allow in the automatic mode to carry out a transition from the 3d-модели of building to the model analytical, and then to the calculation certainly to the element model of building, the calculation of that is conducted with the use of programmatic complexes being based on the use of method of eventual elements. The results of calculation of different variants of the net of eventual elements, generated by facilities of the programmatic complex SAPPHIRE, are considered in the article. As a model for a calculable experiment the fragment of monolithic multistory girderless framework is accepted. The knot of leaning of flag on a column was designed both with the use of absolutely hard body and without him. The step of triangulation was varied in limits a from 1/35 to 1/5 span. The article of analysis is choose the area of lower longitudinal armature along the axis "Х" in the middle of flight. It is set that not dependency upon a type and step of triangulation the use of absolutely hard bodies conduces to the decline of the armature required by a calculation on the average it is Also certain on 6 %., that type and step the triangulations used in the programmatic complex SAPPHIRE substantial influence on the result of selection of flight armature do not render. However it is necessary to take into account that this result is got for charts in that obligatory is eventual elements, the centres of gravity of that are situated in the middle of flight, to what it is needed to aim in the process of creation of computer model of building.

The paper discusses the importance of reconstruction of the existing buildings and structures as energy efficient premises. It highlights that, despite the tendency to demolish residential facilities built in the second half of the twentieth century, in many cities (not only in Russia) these premises are still in demand on the real property market. Because one of the principles of making energy efficient buildings through their reconstruction is to increase the thickness of enclosing structures the paper suggests using composite foam (PENOCOM®) as a certified composite thermal insulation material. The paper sets out the main characteristics of composite foam and provides a summary description of the technology to increase wall thickness with the use of composite foam.

In the article the problems of the technology of aerated concrete products of non-autoclaved hardening are considered and the literature data concerning the study of the influence of various factors on manufacturing technology are analyzed. The results of experimental studies devoted to the study of the role of additives of various types in the formation of aerocrete structure are presented. The influence of three factors was investigated: the type of surfactant introduced into the aerated concrete mix; presence of caustic soda additive; the consumption of aluminum powder on the process of structure formation and the properties of non-autoclaved aerated concrete. The obtained data made it possible to take a detergent powder as a surfactant in further experiments. It has been experimentally confirmed that exclusion of caustic soda from the composition of the aerated concrete mix leads to a decrease in alkalinity, and accordingly the gas release reaction proceeds much more slowly, which leads to an increase in the density of aerated concrete, the appearance of defects on the surface of products, and a significant increase in rejects. The optimal content of aluminum powder in the composition of aerated concrete is determined, which corresponds to grade PAP-1 - 5.75 g.

This article considers the influence of a structuring additive on the physical and mechanical properties of aerated concrete. As a structuring additive, a by-product was introduced into the composition of the aerated concrete mixture by cutting the top layer of the "gorbuschka" in an amount of 10 to 30%. Comparative analysis of the results of physical and mechanical tests of aerated concrete samples with different amount of structuring additive showed that its introduction increases the compressive strength, while simultaneously increasing the density of aerated concrete. At the same time, the value of the constructive quality factor in GB4 (with 20% of the "gorbuschka") is 20.4% higher than in GB2 (with 30% of the "gorbuschka") and 31% higher than for the aerated concrete base composition GB1 (control) that allowed us to take him for the optimal composition in further research.

The aim of the method described in the article is to present a methodical approach to solving (in our opinion for the first time) the problems of ensuring the reliability of single-production machines. A number of principles are formulated, some of which are used from the method for serial machines, and some are new. Instead of the general set of infinite volume, a set of finite volume is used. Uniformity of the aggregate and samples from it is ensured by the equality (with an error of 5-10%) of the main parameters - the minimum resources of the details of one machine, but the details of different for the purpose. The notion of a self-stand is introduced in operational accelerated tests to confirm the estimated parts resources.The article under review contains new results, is written on an actual topic, the presented results can be implemented at machine-building plants with significant economic effect. The article deserves publication in the scientific peer-reviewed journal "The Engineer's Digest of the Don".

The article describes the main principles of the movement around the circumference of the cranes circular steps. It is proved that the defining characteristics of the organization of the movement of the crane on the circle are the geometric parameters of the mutual reversal of the running wheels of the crane, not the observance of the reversal determines the transverse slippage of wheels of the crane, and the shape of the wheels depends only on the elastic longitudinal slide. The result of slides and slippage is firing the head of the rail with one hand and the loss of stability when moving the crane. Stability stability ensures the achievement of the precision targeting of the gripping device. These parameters are the main performance characteristics that should be valued in absolute terms should be minimal.

In the article the results of reinforcement of monolithic reinforced concrete slab bezbalochnyh, different parameters of a finite element mesh, under other equal characteristics. Of course cell model was created by means of PC SAPPHIRE with subsequent transfer of analytical model in LIRA-CAD when creating analytical models used three variants of triangulation, namely: rectangular, triangular and adaptive step triangulation ranged over a wide range-from 1/6 up to 1/30 span. Bearing slabs at columns was carried out on two variants : using an absolutely rigid body and without it. The subject analysis of selected area of the upper longitudinal bearing fittings. During the analysis process was investigated the influence of automatic finite element mesh triangulation on anchor square fittings. Found that in all cases an increase in triangulation step reduces the required for calculating the square top of the longitudinal reinforcement. This reduction may reach 85%, and in case of insufficient quality control finite element mesh is going to cause a serious error in the calculation. When automatically generating a mesh leaf size can significantly exceed step triangulation. All meshes with the zone of transition from AGT to the plate in the form of triangles effect is observed the increase required for calculating reinforcement as you go further away from the brink of columns, that in our view it is illogical. Practical value as the most simple way, has the option of split slabs into rectangular finite elements with a size equal to or slightly greater than the section of the column. without the use of absolute hard bodies.
