Structuring Behavior of Composite Materials Based on Cement, Limestone, and Acidic Ash

Abstract

Abstract—We have studied structure formation of cement stone with the use of silica-containing and inert additives and mechanochemical activation. Rational compositions and the particle size composition of composite binders have been determined by X-ray diffraction, differential thermal analysis, and microstructural analysis, which makes it possible to obtain preset physicomechanical characteristics of cement stone and related concrete. The synergistic effect of pozzolanic and inert additives has been shown to activate hydration processes, densifying the microstructure of newly formed phases.
