2021-6-20 · Limestone is an occurring type of sedimentary carbonate rock found on Earth''s surface. It is formed when crystals of calcium carbonate precipitate out of water containing dissolved calcium. Limestone is composed of minerals such as calcite and aragonite. Limestone consists of 80 percent calcite and Dolomite with more than 50% calcium carbonate.

Physical properties of magnesian lime mortars

2017-8-24 · dolomitic limestone takes place between 510 C and 750 C, a considerable lower temperature than that needed to decompose calcitic limestone alone: 900 C. Consequently, when the calcite is well burnt, the dolomite tends to be overburnt. The decomposi-tion of dolomite is more complex than that of calcite, and can occur in either one stage (Eq. 1 ...
