“Flexural Behaviour of Metakaolin Concrete associated with River Sand and M-Sand”

Abstract

The incessant growth in rate of the cement and result of air pollution which is being qualified throughout the assembly of cement has been directed to diverse research works that were presently being supported out above the world for the complementary resources to cement. Metakaolin is a cementitious pozzolanic solid particularly competent and it could respond promptly with the surplus calcium hydroxide resultant from OPC hydration by a pozzolanic reaction, to yield calcium silicate hydrate and calcium alumino silicate hydrates. This research paper reports the outcomes of an experimental based analysis on flexural actions of merely sustained reinforced beams having a size of 150mm x 250mm x 3000mm made with 10% replacement of cement by Metakaolin and both river sand and Manufactured sand were used as fine collection. The mechanical stuffs such as “compressive strength, flexural strength, fragmented tensile strength and elastic modulus” were analysed for conventional and modified concretes at the age of 28 days. All beams were evaluated with respect to load, deflection, moment, curvature and ductility. The results showed that metakaolin could be deployed as alternative assembly constituents at lesser percentage spare altitudes.
