Abstract
At present all the constructions are executed with conventional granite aggregate concrete. If the granite aggregate is reduced by replacing it partially and fully by Metakaolin pellets as aggregate, the behavior and strength properties are interesting to be investigated. In this study an attempt has been made to use the Metakaolin as the basic ingredient in preparation of artificial pelletized metakaol in aggregate using lime and cement as binders. In the present experimentation, addition of Metakaolin pellets replacing the conventional granite aggregate in percentages of 0, 25, 50, 75 and 100% by volume of concrete and also adding the crimped steel fibre in percentages of 0.50, 1.00, 1.50 and 2.00% by weight. The properties such as compressive strength, split tensile strength, modulus of elasticity and flexural strength are studied by casting and testing around 240 samples consisting of 60 numbers of plain cube specimens of size 150x150x150 mm, 120 numbers of cylinders of size 150mm diameter and 300mm height and 60 numbers of plain beams of size 500x100x100 mm for testing after 28 days of curing.
