Influence of ceramic waste powder (CWP) in strength and durability performance of coir fiber reinforced concrete

Abstract

Concrete is stable in compression but frail in tension. For eliminating the problem, we introduce fibers in the concrete. Ceramic waste powder, when finely ground, can exhibit pozzolanic properties and the coir fiber acts as a natural fiber. Utilizing ceramic waste powder as an additional cementitious ingredient can be advantageous for the environment and theeconomy. A budgetary and sizable plain concrete can be advanced via the unreal of normal Portland cement with ceramicwaste powder. Coir fibers in concrete influences a lesser amount of compressive strength and higher amount of tensilestrength. An investigation is accomplished to test the opportunity of the inclusion of ceramic waste powder as partial cementreplacement and coir fibers were introduced to improve the tensile properties in the concrete. In this study, cement issubstituted with ceramic waste powder in amounts of 0%, 20%, 40%, 60% and 80%. A preliminary investigation revealedthat using 20% ceramic waste powder in place of cement improved the properties of concrete's strength. Further researchreveals that concrete with 0, 0.5%, 1% and 2% coir fiber addition in the concrete with constant 20% ceramic waste powder. Results shows 1% coir fiber addition and 20% ceramic waste powder as cement replacement achieved the strongest qualitiescompared to control concrete. In comparison to the other specimens, the combination of coir fibers with ceramic waste powderimproves the strength properties.
