ROC - Roadheader and crusher

Concrete, usually Portland cement concrete, is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens over time—most frequently a lime-based cement binder, such as Portland cement, but sometimes with other hydraulic cements, such as a calcium aluminate cement.

The phase diagram of the CaO–Al2O3–SiO2–CaSO4–CaCO3–H2O system relevant to cement has been calculated at 25°C and 1 bar pressure. It is composed of 331 stable phase assemblages in equilibrium with the aqueous phase and contains 30 invariant points with 15 solids. Thaumasite appears to be a stable phase with a wide stability domain.

Calcite - Wikipedia

Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO 3).The Mohs scale of mineral hardness, based on scratch hardness comparison, defines value 3 as "calcite".. Other polymorphs of calcium carbonate are the minerals aragonite and vaterite.Aragonite will change to calcite over timescales of days or less at temperatures exceeding 300°C, and vaterite is even ...
