T
he construction industry currently faces a number of challenges due to the depletion of conventional and non-renewable
resources, accessibility and affordability, waste disposal and resulting environmental degradation. Cement is a widely used
man-made material and an inevitable component of the industry. The cement manufacturing is both highly energy intensive and
resource intensive process and their industry is one of the largest producers of carbon dioxide. The concept of geo-polymer is
introduced as an alternative for cement, complying with the notion of sustainability in construction. This demands alternative
materials that minimize the environmental impacts as well as utilising waste by products. This paper aims to find a sustainable
building material using the concept of geo-polymer which is on par with the conventional bricks in terms of strength and durability.
Various proportions of ground granulated blast furnace slag and fly ash was used to form the binder specimens and samples
were casted. The samples were then compared with the conventional burnt clay bricks based on their strength characteristics
and durability. This research established the potential of fly ash and ground granulated blast furnace slag as a source material
for geo-polymer binder to replace cement. In addition, application of geo-polymer in building blocks, as a sustainable alternative
to conventional building blocks and it's suitability in structural and sustainable construction was also verified through the study.
