In self-compacting concrete (SCC) mixture design, polycarboxylate-based superplasticizers (PC-based SPs) usually guarantee the initial workability. However, the time dependent workability of mixtures principally depends on the chemical structure of PC-based SPs and its compatibility with cement. PC-based SPs are the copolymers of chemical structures, which have the potential to be modified to improve their performances. In this study, three synthetic PC-based SPs were synthesized by using radical polymerisation techniques. The effect of these admixtures on setting time of cement pastes and time dependent workability and strength development of SCCs were investigated, respectively.
