- Abstract
The DTA/TG and calorimetric measurements were applied in testing the effect of fine-grained waste expanded perlite as an active component of cement mixtures. The studies were performed with aim to evaluate the kinetics of cement hydration and the modification of phase composition in the presence of additive. The series of mixtures were produced with perlite 2-35 % added to cement. The acceleration of cement hydration was proved due to the pozzolanic reaction between the active amorphous fine-grained perlite. An attempt to elucidate the mechanism of cement-perlite interaction was presented, based on the results of bound water content by TG measurements.
