Abstract

Research is underway to increase the strength of concrete with the addition of chemical
and mineral admixtures. The use of High Range Water Reducers (HRWR) has been increased
many times in the last two decades. In this research the effect of two types of commercially
available HRWR (Superplasticizers) are studied on the properties of concrete in fresh and
hardened state. The strength development characteristics of concrete have been studied with the
addition of the HRWR. The research has shown the selection of appropriate HRWR for the desired
results of concrete in fresh and hardened state is a critical decision for the performance of the
WRWR.
