Laboratory Experiment On Mix Design As Per Is Code Using Fiyash And Plasticizer

Abstract

Concrete is most widely used material which includes cement as binding material. Fly Ash an industrial waste is rich in silica and being industrial waste it is difficult to dispose. Fly ash and presence of lime released by Hydration of cement act as binding material Therefore Fly Ash can replace the cement. This study was undertaken with to study available design methods incorporating Fly ash and suggest a most suitable one for future use. In order to achieve this objective the cubes were cast of M20, M25 of concrete by method of mix design as per IS10262:2009. This Thesis work focuses at the replacement effects (strength) brought by Fly Ash in substitution of concrete. We casted concrete cubes, beams, and are kept for curing for a period of 28days. In this thesis work cement are replaced by fly ash in 5%, 10%, 15%, 20% by weight in concrete and also chemical admixture polygon (water reducer) added in 15%, 20% cement replaced by fly ash cubes which increases compressive strength gradually and also cost effectives.
