Fresh properties of limestone calcined clay cement (LC3) pastes

Abstract

The fresh properties of concrete have a significant influence on the strength and durability of concrete. The flow properties of the cementitious paste have a predominant effect on the fresh properties of concrete. The present investigation focused on evaluating the flow properties of the cementitious pastes prepared from lime stone calcined clay (LC3) with different water cement ratio (0.30, 0.35, 0.40, 0.45) with optimised dosage of three generation water reducers (namely Ligno based, SNF and PCE based) at different time period (5, 30, 60 & 120 min.). Further, the setting time of the cementitious pastes was also determined for all the combinations. The fresh properties of Ordinary Portland Cement pastes and Portland Pozzolana Cement pastes was also analysed and compared with LC3 pastes.
