Annotation: This article determines that the best option to prevent environmental pollution and the diversion of valuable land resources is using ash and slag waste (ASW) for the production of building materials. ASW using is potentially capable for transforming the construction industry and the production of building materials - bricks, dry building mixtures, foam-gas concrete, refractory products. The advantages of involving ash and slag materials in economic circulation as a valuable mineral raw material of technogenic origin, suitable for use in many industries are analyzed. A methodical approach has been developed to detect hydration centers (HC) of different activity on the surface of cement grains. The concentration of hydration centers on the surface of Portland-cement grains is estimated. It has been established that for the studied sample of Portland-cement, the concentration of HC on the surface is much less than the concentration of the corresponding clinker materials.
Keywords: ash and slag waste, binders, Portland cement, concretes, hydration centers, topochemical reactions.
