Comparative study of Conventional Clay Bricks and Mechanically Pressed Fly Ash Brick

Abstract

This work tells the production of economical bricks compare to conventional clay bricks using fly ash. The structural defects due to bricks made from conventional clay are compared to that of bricks made from fly ash. The physical and mechanical properties and the durability of the bricks were then compared to those of similar bricks with no added fly ash, to assess whether the quality of the bricks had been enhanced or at least maintained. Tests like Compression test (UTM) ASTM C67, Mortar adhesive test ASTM C952-12, Water absorption, density is performed. Mould of size 9 by 4.5 by 3 inches is prepared by using fly ash of 40% to 70% by weight and the results are compared. The fly ash bricks produced in this study seem to be suitable for use as construction material. The production of this type of bricks will certainly contribute to the recycling of the fly ash and hence minimize the negative impact of the fly ash landfills on the environment. On the other hand, the reduction in clay usage to produce conventional clay bricks will help to protect the environment.
