Chemical reaction of limestone with C3S and C3A | Cement

Chemical reaction of limestone with C3S and C3A. The hydration rate of C 3 S is accelerated in the presence of limestone probably because of the dilute effect and the multiplied nucleation sites. Jean Pera et al. reported that the total heat resulting from pure C 3 S hydration was 145 joules while that of the mixture (50%C 3 S+50%CaCO 3
