Effect of Chemical Admixtures on Hardened Properties of Ordinary Grade Concrete

Abstract

The efforts were made to understand the possible differences between plasticizers and super plasticizers. The result of tests conducted on concrete in the presence of plasticizers and superplasticizers. The objective was to observe the change in mechanical properties under the influence of plasticizers and superplasticizers at various dosages level. The result of the treated mix was compared with the control mix (mix without admixture). Observations were made on solid phases of concrete, to note the variation in properties at constant and reduce water cement ratio. From the experience and knowledge gained from this course of study both, plasticizers and super-plasticizers not only improved workability at constant water cement ratio but considerably enhanced the compressive strength at reduce water-cement ratio with slump remaining unchanged, At every stage superplasticizers were known to perform better than plasticizers.
