Jan 29, 2014· To make Portland cement—the most common type of cement—powdered limestone is heated in a rotary kiln. As a source of calcium, it joins with powdered clay to produce a product called clinker, which is then ground with a source of sulfate, like gypsum. It is mixed with water, sand and crushed rock to create concrete.
The exact amount of substitution depends on the cement and the fineness of the limestone. They suggest that, due to the mitigating effects of the carboaluminate formed by the reaction of carbonates with C3A, up to 25% of the gypsum could be replaced with limestone without any significant change to setting times or strengths.
