Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate

Limestone is widely used in construction, both as a component of cement, and an additive in the production of ready-mix concrete. Good results are achieved by using limestone in the technology of self-compacting concretes, in which it is important to ensure proper rheological properties (as low as possible yield stress and adequate viscosity) ensuring the possibility of self-compacting [1]. 1
