STUDY OF THE PROSPECTS OF USING FLY ASH IN CONSTRUCTION

Abstract

The prospects of using fly ash, which occurs during the burning of coal in thermal power plants, in construction were studied. Fly ash is considered as a secondary product that can be effectively used to improve the quality of building materials and reduce the negative impact on the environment.The impact of ash on the strength of building materials, as well as their resistance to aggressive factors, is considered. In addition, the impact of using ash on the energy efficiency of building materials and reducing carbon dioxide emissions is considered.Ways of processing waste, which allow to significantly reduce the negative anthropogenic impact on the environment, are considered. It was found that gold and varnish waste can be used in construction, agriculture, and water treatment technologies. Ash and slag waste is most widely used in the construction industry as a ready aggregate and raw material. In particular, the use of thermal power plant slag for road construction is widespread.An overview of modern research and experience in the use of fly ash in construction is carried out, and examples of successful cases of its application are given.The research results show that the use of fly ash in construction has great potential. It allows to reduce the use of primary materials, improve the quality of construction materials and reduce the negative impact of the construction industry on the environment.In general, the use of fly ash in construction is a promising direction that contributes to sustainable development and reducing the negative impact of the construction industry on the environment. It allows efficient use of waste and ensures the creation of environmentally sustainable and energy-efficient building materials
