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.
