Perform Study of Water reducer and Super Plasticizer on the Properties of Concrete

Abstract

Admixtures have been used in the concrete industry for many decades. They are usually by-products of particular primary material that eventually finds an application as a concrete admixture. Specific requests from the concrete industry created a need to develop polymers with the desired performances. Requests for high strength and high performance concrete top the list. Design codes have been updated in many countries for the use of concretes with earlier unknown strength and mechanical performances. The challenge for the construction industry is to design, manufacture and to deliver such concretes with locally available materials. These concretes should not only maintain workability but also be able to produce strong, durable and workable concrete. Water reducers and super-plasticizers, which allow a reduction of water content and at the same time give extended slump retention, have made the production of such high strength and high performance concretes a reality. This study has been carried out to determine the effects on the properties of concrete and its performance using commercially available chemicals.
