Abstract
This study mainly inspects the production of
durable and environment friendly concrete by utilizing Fly Ash
[FA]. This fly ash is the byproduct occurred from the coal based
thermal power plants as cementitious material. High Volume Fly
Ash [HVFA] Concrete is topic of discussion as it utilises FA as
cement replacement to greater extent [more than
40%replacement]. Owing to their pozzolanic properties, FA is
examined as partial replacement of cement with varying
proportions [40%, 45% and 50%by weight] in this study as
HVFA concrete. The grade of concrete adopted to observe the
performance of HVFA concrete is M30 and were tested for
analyzing their strengths-compressive ability, strength on the
flexural capacity and their split tensile strength, after curing the
molded samples 7 days, 28 days and 90 days respectively.
Keywords: Coal Ash, Environmentally friendly, Cement Replacement.
