Limestone powder can accelerate the hydration of clinker, notably C 3 S, by providing nucleation sites for the precipitation of calciumsilicate hydrates . On the other hand, the high affinity of clinker (C 3 A) and limestone (CO 2 ) can modify the process of hydration and form carboaluminate phases rather than sulphoaluminates [ 43, 44 ].

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 .
