Comparative Study on Fly Ash Bricks and Burnt Clay Bricks

Abstract

In the today’s world, every nation is spending the major portion of its treasury on building infrastructure and maintaining pre-existing groundwork. Attention to economic aspects is given prior to the initiation of the project implementation. Regarding the construction industry, masonry work is allocated a huge sum of money because traditionally the skeletal form of the structure is built first where brickwork constitutes the main share of the total budget. Keeping into view the need for using the cheap but good quality material, fly ash bricks in place of red clay bricks, in my opinion, could assist the construction firms to provide clients with the reduced budget product without compromising the quality parameters. In this project, other than highlighting the fly ash bricks characteristics, raw material availability to cast the bricks, comparability with red clay bricks and analysis about ongoing factory production in Pakistan, a careful observation has been made on the impacts fly ash bricks have has on the environment as well as the introduction of gypsum-lime binder fly ash brick in place of cement materialized brick. The purpose behind incorporating gypsum/lime in place of cement/course aggregate without removing the fly ash and sand composition is to lessen the price without disturbing the original strength, quality and specifications of already proposed cement fly ash brick. Referencing several research works already done in India and other countries, proportioning have been set where efforts are made to increase the compressive strength alongside making bricks less water absorbable. In order to make project a successful accomplishment, we got in touch with all the fly ash brick factory owners and visited them for getting a knowhow about different material proportions as set-out by them. Moreover, our own designed were casted in three different factories in order to check the equipment efficiency.
