Technology of Obtaining Multilayer Structures Variational Structure

Abstract

The current state of the market for the production of aerated concrete in the Russian Federation and its prospects are considered. Every year, the production of cellular concrete is constantly increasing due to the construction of new plants that produce the most advanced technologies with the use of modernized equipment. However, there are technological and prescription raw materials issues. Therefore, the development of new technologies for the production of cellular concrete products due to the improvement, modernization and development of fundamentally new technological methods is highly important. The technologies for producing multilayer cellular concrete designs with a variational structure are considered. This allows to get products with high performance that meets modern requirements for energy efficiency and durability. The method of layered pouring of a cellular concrete mixture into a form with removable partitions is proposed for creating a single-layer construction of cellular concrete with variable density over the section. The integral principle is shown from small ones at the periphery, to large ones in the middle of the block, taking into account the rheological characteristics of cellular concrete mixtures and the foaming time. They provide the possibility of obtaining a design with a smooth transition of the structural heat-insulating layer to the layer without seams, air gaps and other possible defects arising during the molding of three-layer structures from non-uniform materials.
