Performance analysis of self compacting concrete without super plasticizer

Abstract

The use of self compacting concrete (SCC) in civil engineering works has become an attractive option which produces confident cohesive concrete. This paper reviewed the feasibility of preparing a SCC without using super-plasticizer but with only mineral admixtures that are available locally, with the coarse aggregate size of with 20 mm well graded aggregates which is entirely a different way of preparation of SCC. The enhancement aspects were tested and ascertained with the EFNARC guidelines. The hardened properties of SCC were tested and compared with control concrete of M25 grade. In the preliminary investigation, mechanical properties of the SCC which have been prepared by the above said method were tested by its unique testing methodologies. Based on the test results, in the second phase, the flexural behavior of the SCC specimens, using beam specimens were tested for its load carrying capacity by loading frame. In both the phases of investigation, the results revealed that this type of SCC will be promising and effective combination to that of the traditional type of SCC prepared by Glenium product and also cost effective.
