A Study on the Substitution of Rice Husk Ash with Natural Sand of Cement Concrete

Abstract

Researchers from all around the world are currently investigating the feasibility of utilizing agricultural and/or industrial wastes as a resource for the building sector. In addition to saving money, recycling these materials could aid in making the planet a cleaner, greener place to live. Fibrous waste products such as sugar cane bagasse and ethanol vapour are produced during the sugar refining process.. In this study, fine aggregate in concrete was replaced with rice husk ash at the volumetric percentages of 0%, 10%, 20%, 30%, and 40%. Testing was done on both fresh concrete, using methods like the slump cone test, and on hardened concrete, using methods like the compressive strength, split tensile strength, and flexural test. The slump value of the samples was found to decrease when the rice husk ash level enhanced. Up to 20% substitution of rice husk ash with fine aggregates resulted in an improvement in mechanical characteristics.
