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 ].
