Physicochemical Engineering of Composite Cements for Shotcrete Applications with the Recycling of Production Waste

Abstract
A methodology for the physicochemical engineering of shotcrete based on composite cement was proposed. It involves the use of activated and homogenized waste materials (coal ash and construction concrete debris) in a vibratory mill, which allows for the management of the structural formation processes of composite cement through the affinity of structures and the appearance of high-strength new compounds. The mechanism for managing the structural formation of high-density concrete composites was substantiated. This mechanism is based on the complex influence of components of composite cement with an optimized composition and granulometry. For the first time, the dependencies of the impact of production waste characteristics (composition and ratio of initial components, as well as their milling parameters) on the improvement of the performance characteristics of synthesized building materials were evaluated.
