An Experimental Study on Strength and Durability of Concrete with Addition of Cow Dung Ash and Glass fibre

Abstract

In civil engineering constructions cement is the main binding material for concrete preparation. The
production and consumption of cement in construction field are increasing day by day. It may cause more environmental
problem due to emission of huge amount of pollutant gases to the atmosphere. Many cementitious materials are used as
partial replacement of cement. This will reduce the necessity for cement production, thus reducing the environmental
effects. This research paper presents the results on the study by using Cow Dung Ash as a partial replacement of cement
in the 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 and curing for the periods of 7, 14, and 28 days
before testing for the Compressive strengths. In this paper cement replacement levels were selected to study the effects of
CDA on compressive strength, acid and chloride resistance in concretes. The M25 mix design for the proposed concrete
mix is done. The present investigation has also shown that an addition of 0.5% glass fibre to concrete makes it stronger
and more durable. Results showed that 8% replacement of cement by cow dung ash produces a considerable increase in
compressive strength. From durability tests, it is observed that the CDA concrete with glass fibre has the ability to resist
acid attack and chloride attack
