Abstract
Composite cement is a binder system containing a mineral component that improves the construction and technical properties of cement. During separate and combined grinding of composite cement components in a high-energy centrifugal impact mill the mechanical activation of the mineral additive is carried out and mechanocomposites are formed, affecting the hardening and properties of the finished product. Hydration schemes for composite cements of separate and combined grinding are proposed. It is shown that during the hydration of composite cements, X-ray amorphous calcium hydrosilicates and hydroaluminates are formed, which crystallize under nonequilibrium conditions according to the non-classical kvataron mechanism. This leads to the formation of a fractal structure of cement stone with high early strength.
