Experimental Investigation on Concrete using Egg Shell Powder, Metakaolin and Rice Husk Ash

Abstract

Nowadays environmental problems are more and more significant. The industrial area produces lots of waste materials and CO2, respectably. One of the most effective ways to solve these problems is the utilization of these waste materials. One choice of the usage of the waste materials is in the construction industry. The most common and widely used building material is concrete. The most significant and indispensable part of concrete is cement. The production process of cements from its raw material produces a lot CO2. The most effective way to decrease the CO2 emission of cement industry is the substitution of a proportion of cement with supplementary cementing materials. Ternary blended concrete is developed by partial replacement of cement with metakaolin, Egg shell powder and rice husk ash in M20 concrete mix design". In this research the experimental investigations carried out in two phase, First the Experimental work was carried out to investigate the effect of egg shell powder by partial replacing cement and keeping same water cement ratio, The concrete mixes had 0%, 2.5%, 5%, 7.5%, 10%, 12.5% of ESP (Egg Shell Powder), replacing cement partially and compressive, split and flexural tests are conducted. After getting the optimum percentage of Egg shell Powder, the next Experimental work was carried out to investigate the effect of Meta kaolin, Rice husk Ash and Egg shell powder by partial replacing cement and keeping same water cement ratio to ordinary concrete & Metakaolin, RHA and ESP. The concrete mixes had 0%, 5%, 10%, 15%, 20% of Meta kaolin ,RHA with 5% ESP, replacing cement partially. From this research the results are much better as compare to conventional concrete." Keywords: Egg shell powder (ESP), Rice husk powder (RHA), Metakaoline, Split Tensile, compressive and Flexural Strength.
