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.
