Abstract

This study investigated the compressive strength and workability of RHA blended concrete treated with polycarboxylate ether-based superplasticizer (PCE). A total of 45 cylindrical specimens (6"x12") were casted using nine mix proportions consisting of five specimens per batch (0% RHA, 5% RHA and 10% RHA at 0.4, 0.45, and 0.5 w/c ratio). The dosage of PCE is 2% by weight of cement. The specimens were cured for 28 days. Results show that all the batches produced slumps higher than 100mm. Concrete with 5% RHA at 0.4 w/c ratio was found out to be the optimal mix proportion showing the highest compressive test results.
