Study on Correlating Properties of Cement Paste and Concrete

Abstract

Concrete is a composite material consisting of aggregates, binding material, water and admixtures. It is the most widely used construction material on earth. This paper is a study on loss of workability, setting time, property correlation between paste and concrete for various admixture and superplasticiser dosages. The mineral admixtures considered are Fly ash and (Ground granulated blast furnace slag) GGBS with superplasticiser Masterglenium SKY 8233. The flow analysis in paste can be used as a guideline for finding saturation superplasticiser dosage. The study on setting time shows than results of paste and concrete are comparable. It is also found that saturated superplasticiser dosage in paste and concrete can be correlated for better compressive strength. By this study, tests on the paste can be used as guide for optimising flow behaviours, setting time, compressive strength in concrete without doing tedious tests in concrete.
