Cement is manufactured by calcination of calcium, silica and alumina sources such as limestone, clay and sand [4].Generally, these raw materials are locally sourced and undergo several sequential operations such as quarrying, homogenising of raw meal, preheating, calcination, clinkerisation, cooling, grinding, storage and dispatch.
Dolomite also helps prevent surface cracking caused by freeze/thaw cycles. Studies show that the use of dolomite in concrete decreases the risk of frost action cracking. Concrete with high concentrations of dolomite tends to crack less easily than concrete with lower levels. Dolomite has many useful properties.
When used as a partial replacement of cement in concrete, dolomite powder reacts with the hydration products of cement to form calcium magnesium carbonate hydrates, which …
