Experimental Investigation on Bricks by Using Cow Dung, Rice Husk, Egg Shell Powder as a Partial Replacement for Fly Ash

Abstract

The usage of solid waste materials in the production of construction materials has received considerable attention across the world. Various types of bricks are used in construction. The most common are conventional bricks. Owing to the exploitation of large amount of natural resources in the manufacturing of conventional bricks, we provide an alternative solution for conventional bricks through this project. The present study investigates the feasibility of using rice husk powder, cow dung and egg shell powder in the manufacturing of fly ash bricks. Fly ash bricks of different compositions with rice husk, cow dung and egg shell powder were prepared in steel moulds. After casting, the brick samples were stored at 35 C and a relative humidity of 50% until the ages required for testing. The brick samples were checked for dimensions and visible defects. The effects of rice husk, cow dung and egg shell powder contents on the engineering properties of the solid bricks were also investigated. The test results showed that all brick samples exhibited good compressive strength. The compression strength ranged between. It is concluded that the manufactured bricks acquired sufficient strength and became more economical.
