The article considers the possibility of improving the physical, mechanical and environmental properties of polymer concrete by changing their component composition depending on the requirements for the operational characteristics of the construction object. Currently, the research of scientists is aimed at the development and implementation in construction practice of compositions of light building materials, the range of densities of which varies depending on the tasks set. Such an additive as glass, changing the physical properties of the material, significantly improves its characteristics, there are the following types of such concrete: glass concrete with fiber, concrete with optical fiber, with cullet, and also a solution where glass is used as a binding element. Liquid glass, when added to concrete, helps to improve the stability and strength of plaster and concrete structures. When using this material, you can find a lot of positive things. The environmental friendliness of the material expands the scope of its use, which is very important at the present time. The new material is easy to obtain, is made from affordable materials, has improved physical and mechanical characteristics, which makes it competitive among a wide range of products on the global construction market.
