Abstract: For civil engineering the basic need is to produce high quality and high strength concrete. superplasticizers are used as high range water reducer and they improve the workability of concrete and mortar. In the present work several experimental programmes have been carried out in order to study the effect of Vinsuperplast on RHA blended cement. 2% Vinsuperplast with RHA blended cement and ordinary Portland cement increases the hydration and strength of cement which was measured by consistency measurement, setting time, non-evaporable water content, and free lime determination. 20% RHA blended cement gives better results in comparison to 10% RHA blended cement. The hydration mechanism of RHA blended cement with Vinsuperplast were tried to understand by using XRD, DSC and SEM techniques.
