Beginning with the 1970s many specialists have been dedicating their works to investigation of the possibility to use concrete modifications of non-organic materials containing amorphous silica. Almost any industrial product is beginning with raw materials obtained from the planetary interior or formed on its surface. That’s why the problem of selective choice and utilization of industrial waste is of a global character, so it is of great importance. Currently, the attention of scientists and engineers is attracted by the widespread use of high-strength concrete, different from the usual one by high content of cement stone, lesser grain size, multi-component, increased specific surface area of the filler. The performance properties of concrete to a large extent depend on the properties of aggregate and water content. It is known that empirical way to search for improving the strength of concrete has always been a laborious and time-consuming. In this regard, the actual conditions for forming a preliminary study of high-strength concrete structure have been investigated, as well as the role of processing methods in the process and nature of the impact on the quality of a concrete structure.
today energy saving and energy efficiency improvement in Russia are priority directions of the country’s energy policy. First of all, when creating an energy-efficient house, it is necessary to think about preventing heat losses through enclosing structures, and only then about reducing lighting costs, optimizing the work of building engineering systems, and the introduction of alternative energy sources. Materials for thermal insulation, the most important characteristic of which is the thermal conductivity, do the main role in the provision of optimal conditions of indoor air. The creation of thermal insulation solutions with improved thermal protection properties is a very acute problem at the moment. In this connection, the purpose of this work was to create effective compositional binders that contribute to the reduction of the density of thermal insulation materials.
Within the framework of the energy-saving program and the development of housing construction of the Russian Federation and the implementation of the Federal Law №185-FZ “On assistance to the reform of housing and communal services”, the creation of new effective building materials with high performance and thermal protection characteristics that can compete with foreign analogues is of great importance.
This article presents new approaches to improve the efficiency of dry heat-insulating mixtures, taking into account the law of affinity structures, which provides for the design of composites using fillers and composite binders of reduced density. Thermal insulation solutions on the basis of dry construction mixtures have superior technology, physical and mechanical and operational performance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
