A Study on Cement Partially Replaced with Chalk Powder and Coconut Fiber Ash with the Addition of Asbestos Fiber

Abstract

Abstract: Concrete can be defined as a building material that can be composed by mixing gravel or broken stone, sand, cement, and water. The mixture can be poured into any shape, size of mould, which on hardening gives a solid stone like mass, the strength of hardened solid mass can be increased by adding admixtures. The main aim of the admixtures is to enhance the properties to some extend of the desired solid mass. In common man language concrete can be defined as mixture of paste and aggregates. The partial replacement of aggregates is need for the future generation of concrete structures for the environment supportable. The depletion of the natural resources gets exhausted. We have think over the alternate replacement of the materials. In present work the cement partially replaced by Chalk Powder, Coconut Fiber Ash with the addition of Asbestos Fibres. Optimum value of strength in compression, split tensile and flexure came at 18% replacement with 0.6% addition the strength is higher than conventional concrete. The workability of mixture increases and after that there is decrease in the workability of the concrete when we increase the percentage of Chalk Powder, Coconut Fiber Ash. A series of experiment were carried out to measure the compressive strength, split tensile strength and flexural strength of the concrete. The results showed that the compressive strength, split tensile strength and flexural strength increases with the adding of the Chalk Powder, Coconut Fiber Ash with the addition of Asbestos Fibres.
