An Experimental Investigation on Strength of Concrete Made with Cow Dung Ash and Glass Fibre

Abstract

The consumption of cement in concrete industries has been increasing day by day to fulfil the needs of infrastructure due to growing population, industrialization and urbanization. The production of cement poses environmental problems due to emission of gaseous pollutants. Cow dung is used as fuel for the domestic purpose, which generates solid waste as ash. This paper presents the result on the study for the use of Cow Dung Ash (CDA) as partial replacement of cement in production of concrete. This replacement was designed to study the effects of adding Cow Dung Ash (CDA) in various percentages by weight (6%, 8%, 10%, 12% and 14%) of cement. To strengthen the CDA concrete and making it more durable 0.5% glass fibre is being added, as it is an economically strong material, have excellent flexural strength, crack resistance and can also be used as an alternate material for concrete construction. The M25 mix design for the proposed concrete mix is calculated. Results showed that up to 8% replacement of cement by cow dung ash there was an increase in compressive strength. The experimental work was carried out with M sand confirming to zone I as fine aggregate in concrete.
