Rheological and hydration behaviour of cement pastes containing porcelain polishing residue and different water-reducing admixtures

The pozzolanic activity and great availability of ceramic wastes (such as porcelain polishing residue – PPR) have increased their usage as supplementary cementitious material. However, studies investigating the effect of water-reducing admixtures on the early-age performance of cement-based materials containing such wastes are still lacking. This work investigated the effect of a lignosulfonate-based plasticizer (PL) and two...
