EXPERIMENTAL STUDY ON MECHANICAL PROPERTIES OF CONCRETE WITH SUNFLOWER SEED HUSK ASH AS PARTIAL REPLACEMENT OF CEMENT

Abstract

The present study depicts on mechanical properties of concrete withSunflower Seed Husk Ash (SSHA) as partialreplacement of cement. Concrete made with Ordinary Portland Cement is the most widely used material in all thecountries. Hence the production of Ordinary Portland Cement is expensive and ecologically harmful. Cement industriesreleasing huge quantity of CO2which pollute the environment. Structural concrete can be produced using sunflower seedhusk ash to meet strength and other requirements. In this project work, various percentages of SSHA added with concreteandthe mechanical properties where studied. The effects of SSHA as partial replacement of cement on concrete propertieswas investigated. Concrete was produced by adding various amount of SSHA (2.5%, 5%, and 7.5%). From the literaturereview it has been noticed that the replacement of sunflower seed husk ash in concrete was very successful in reducing ofunit weight, compressive strength, splitting tensile strength and freezing-thawing resistance. But water absorption rate isincreased after 28 and 90 days. Based on experimental results its physical and mechanical properties show that concreteproduced with sunflower seed husk ash has great potential as a low cost lightweight building material.
