Abstract: In this study, the effect of the polycarboxylate-based superplasticizer (PCE) main and side chain length variation on the admixture requirement to provide the target slump-flow value (27±2 cm) and the time dependent slump-flow performance of mortar mixtures with different C3A content was investigated. For this aim, a total of 12 mortar mixtures were prepared by using Portland cement with four different C3A ratios (2%, 3%, 6%, 9%) and three different main and side chain lengths PCE. According to the results, generally, the PCE requirement for target slump-flow value increased by an increment of the C3A ratio. The admixture requirement for the mixture containing PCE with medium main and side chain length for target slump was 28-41% and 7-12% lower compared to those containing PCE having a long main chain and short side chain and the PCE having a short main chain and long side chain, respectively. On the other hand, time-dependent slump flow performance of mixtures containing PCE having medium main and side chain lengths; compared to those containing long main chain and short side chain and short main chain and long side chain, in the range of 6-22% and 13-30% lower, respectively.
