Method of obtaining calcium silicate for construction [PDF]

open access: yesНанотехнологии в строительстве, 2021
Introduction. Calcium silicate is one of the well-known building materials. Its structure determines the ability of such nanostructured additives to form a secondary structure – a fractal (volumetrical) network with which cement grains interact.
