Green bricks from waste

Abstract

This paper presents the findings on an investigation done on the use of Quarry dust, Fly ash and Billet scale in developing bricks. Bricks were made with various proportions of those materials and cement. Tests for fresh density, compressive strength, and water absorption were conducted. The compressive strength of bricks ranged from (7.2-26.3) MPa, the water absorption fell in range between (13-14.26) %. The optimum ratio of Fly ash and Billet scale is 1:1. It is shown that bricks with enhanced properties can be developed using these industrial wastes. © (2013) Trans Tech Publications, Switzerland.
