Limestone powder is a byproduct of the limestone quarry, and it has been used in cementbased materials for many years. In 1938, Bessey could react with cement to form calciumcarboaluminate. The formation of calciumcarboaluminate was influenced by the amount and fineness of LS, but it had little effect on the compressive strength of mixtures .
