Abstract:

High strength and self-compactability can be achieved by incorporating mineral admixtures without losing homogeneity of the concrete mix. This study aims to focus on the possibility of using metakaolin as a partial replacement of Portland Pozzolanic Cement to produce HSSCC for a grade of M60. The self-compactability properties were evaluated as per EFNARC guidelines and hardened properties were evaluated by compressive and split tensile strength. All the HSSCC mixtures developed using metakaolin exhibited good self-compactability properties. The need for viscosity modifying admixture can be fully avoided for high replacement level with metakaolin. Optimum replacement level of metakaolin was found as 15% in terms of compressive strength, beyond this compressive strength was decreased but remained higher than the control concrete. Higher content of fines has not influenced the split tensile strength.
