Application of industrial waste for the production of expansion components

Abstract

The opportunity to obtain building materials with high physical and mechanical characteristics attracted scientists and practitioners in the search for the use of cheap industrial waste, which would reduce material and energy consumption, having obtained materials with the specified properties. Blast-furnace and metallurgical slags are of particular interest for solving these problems, since they are characterized by a predictable chemical composition and are environmentally friendly. The current level of development of concrete technology involves the widespread use of various additives in concrete. The use of additives is rightly considered as one of the most versatile, affordable and flexible ways to control the technological parameters of building materials. As a result of the use of expansion additives, it is possible to improve the structural characteristics of concrete, reduce shrinkage deformations, accelerate the rate of strength increase, and increase durability. Ultimately, it is possible to qualitatively improve the construction and technical properties of the structure.
