STRENGTH STUDIES ON BANANA FIBRE CONCRETE WITH METAKAOLIN

This study investigates the combined effect of deploying Metakaolin and banana fibers (BF) on mechanical properties of hardened concrete of grade M40. Banana has been used as the partial replacement of cement by 0, 10, 15, 20, 25 and 30 by weight and BF has used as volume substitution by 0, 1, 2, 3, 4, 5 and 6%. In our present investigation, banana fibres having 40mm length were used. Compressive strength and splitting tensile strength are determined by using various combinations of Metakaolin and BF. A notable improvement is being noticed in the strength properties of concrete when Metakaolin is used. The addition of Metakaolin to the concrete improved the properties of strength as well as durability to a great extent. On the other hand, the addition of banana fibres to the concrete results in the reduction of permeability and the improvement in the crack resistance eventuallY
