Impact of Metakaolin and Steel Fibre on Mechanical Properties of Concrete

Abstract

This study was based on experiments conducted to see the effect of Metakaolin (MK) concrete and Metakaolin (MK) concrete along with steel fibre on mechanical properties of concrete. The cement was replaced by metakaolin by 4, 8, 12, 16 and 20% of total weight of binder. Steel fibre (SF) used for the study has aspect ratio 83.33. Total 21 mix proportions were prepared for study. Compressive, split tensile and flexural strength tests were used to analysed the effect of metakaolin and steel fibre on concrete samples. These tests were conducted after the 28th day and 90th day of curing period. The present conducted study revealed that the incorporation of steel fibre and metakaolin (MK) shows significant changes on mechanical properties of concrete.
