The difference between heavy and light calcium carbonate. Heavy calcium carbonate is washed and milled in natural ore water to achieve the whiteness and fineness of coating. Light calcium carbonate is obtained by calcining and water dissolving CaCO3. In the application of coating, the heavy calcium is relatively safe, and the dry covering power ...

The primary advantage of CSA cements is that concrete made with CSA instead of portland cement often achieves compressive strengths of in excess of 5000 psi in 24 hours; with CSA’s, it’s possible to achieve 28 day strength in 24 hours. This is the main reason CSA’s are used in place of ordinary portland cement (OPC) for certain applications.

CSA Cement, also named Calcium Sulpho Aluminate Cement with grade: 42.5, 52.5, 62.5, 72.5, 82.5, 92.5, is a hydraulic binder based on calcium sulpho aluminate, rather than calcium aluminates which are the basis of Calcium Aluminates Cement or calcium silicates which are the basis of Portland Cement.

The most obvious differences between light and heavy calcium carbonate lie in pH value, fineness, and particle shape. The shape of light calcium carbonate is mainly spindly, while that of heavy calcium carbonate is mainly irregular particles, and the differences between fineness and shape result in the difference of apparent specific gravity.

What are the differences in these cement types and how are they tested, produced, and identified in practice? In the most general sense, portland cement is produced by heating sources of lime, iron, silica, and alumina to clinkering temperature (2,500 to 2,800 degrees Fahrenheit) in a rotating kiln, then grinding the clinker to a fine powder.

A combination of low calcium content and low burning temperatures allows CSA cement to yield concrete with a lower carbon footprint. When used as a shrinkage-compensating additive to traditional cement, CSA can also improve sustainability through a decrease or total elimination of shrinkage, resulting in an increase in longevity.
