Maximal use of local natural substandard raw materials in the technology of repairing concrete and ferro-concrete structures determines the possibility of obtaining modified repair compositions with improved characteristics based on barkhan sands in order to restore the bearing capacity of products and...

The article presents the results of wind modeling with the effects on high-rise building in the aerodynamic tunnel; the data were applied to complete the calculations of the load-bearing structures with wind and seismic loads. This resulted in obtaining the forms of natural oscillations of a high-rise...

The paper studies the influence of composition and technological factors on rheological indicators of concrete mixes modified by various chemical additives. The rheological and water-reducing efficiency of super- and hyper-plasticizers in cement suspensions depending on their addition procedure was studied....

Technogenic wastes, which utilization is an urgent issue in developed countries, is quite interesting for the production of fine-ground filler used to produce modern high quality concrete. The amount of technogenic waste (or technogenic raw materials, secondary raw materials) is so big that some sources...

The paper presents the study of the impact of technogenic mineral filler (TMF) on the basic properties of high-quality concrete mixtures and concretes. There are principles of rational use of secondary technogenic raw materials in the form of concrete scrap, crushed bricks, ashes and slag mixtures in...

In order to make the nature of asphalt concrete testing close to real conditions of actual operation in road pavements, it seems rational to implement a cycle of tests. During the course of test cycle the consistent accumulation of the results of integrated im-pact of climatic factors will be performed...

The issue of quality, reliability and safety of finished bearings is considered. The basis of the quality management system is the process approach; the monitoring program is considered as an example

One of the current areas of building materials science is the development and implementation of highly efficient facing materials, which can significantly improve the architectural expressiveness of human settlements. Used in modern construction autoclave silicate materials have rather low decorative...

The present stage of innovative development of the country is characterized by considerable changes caused by the introduction of digital technologies into the economy and the social sphere. The measures aimed to improve the institutional conditions of business, production of innovative products taking...

The study covers the optimization of physical and mechanical properties and operational characteristics of fiber concrete that include complex influence of a binding agent on structure formation. The optimal composition of concrete ensuring the maximum static and dynamic strength was selected (impact...

In the process of using drilling muds in the oil and gas reservoirs, bentonite clay accumulates, which precludes their development, if not swelling it with carbon dioxide. The objection of this paper is to present the results of the sedimentation study and the degree of bentonite swelling depending on...

The article analyzes innovative construction technology - additive manufacturing - and prospects for using it in the Chechen Republic with complex engineering and geological conditions of construction sites (soil subsidence, high seismicity, etc.). Technologies based on modern composites and traditional...

The use of fly ash from power plants as a component of paving asphalt concrete has been studied by many scientists for over 100 years. However, there are conflicting data of their effect on properties of composites. The reason for this may be insufficient understanding of the role of fly ash composition,...

The article proposes a "stock" - an improved technological process of parts production. During the research it was found that the reason of the failure of hydraulic cylinder is charged rod surface, obtained after the grinding process. This factor leads to intensive wear of the sealing system and subsequent...

The article deals with the main peculiarities of phase- and structure formation in the system "cement-basaltic-fiber" with the use of initial and heat treated basaltic fiber. The authors used heat-treated fiber by the authors' method suggested earlier, which provide its recrystallization. As the result,...

The paper presents the most optimum concentration of crushing dust of concrete scrap (CDCS) ground in the laboratory spherical mill to a specific surface of 4000 cm2/g for further replacement of a part of cement. High strength parameters are achieved at partial replacement of cement with various concentrations...
