Innovative Solutions in the Production of Dry Construction Mixtures Based on TPP Fly Ash

An overview of modern research and experience in the use of fly ash in construction is carried out, examples of successfulcases of its application are given.The prospects of using fly ash, which occurs during the burning of coal in thermal power plants, in construction were studied.Fly ash, which is a byproduct of coal combustion, has great potential for reuse in the construction industry, which contributes toreducing the environmental burden and increasing the efficiency of the production of construction materials.The paper discusses in detail different methods of fly ash activation, such as mechanical, chemical and thermal activation, aswell as combined approaches that combine these methods to achieve optimal results. Mechanical activation involves increasingthe specific surface area of ash by grinding it, which helps to increase its reactivity. Chemical activation involves the use of various chemical reagents to increase the activity of ash, and thermal activation is based on increasing the solubility of silica and alumina with increasing temperature.Particular attention is paid to the use of nanomaterials, such as nanosilica, nanotitanium and nanoalumina, which cansignificantly improve the properties of construction mixtures. Nanomaterials help increase strength, reduce porosity and improve water resistance of mixtures. The use of polymer additives, such as polyvinyl acetate, latexes and polyethylene glycol, which increase the adhesion, elasticity and water resistance of building materials, is also considered.The influence of ash on the strength of building materials, as well as their resistance to aggressive factors, is considered. Inaddition, the impact of using ash on the energy efficiency of building materials and reducing carbon dioxide emissions isconsidered.The development of new formulations of construction mixtures using fly ash helps to increase their strength, durability andenvironmental safety. The article gives examples of the practical application of such mixtures, in particular, in self-leveling screeds for floors, plaster and putty mixtures, adhesive mixtures for tiles and waterproofing materials. Key benefits of these innovative solutions are highlighted, including lower production costs, improved material performance and reduced environmental impact.The research results show that the use of fly ash in construction has great potential. It allows to reduce the use of primarymaterials, improve the quality of construction materials and reduce the negative impact of the construction industry on theenvironment.The article emphasizes the importance of using fly ash and innovative additives for the sustainable development of theconstruction industry and suggests promising directions for further research in this field.
