Abstract

Fly ash is a residual material of energy production using coal, which has been found to have
numerous advantages for use in concrete. Some of the advantage include improved workability,
reduced permeability, increased ultimate strength, reduced bleeding, and better surface and
reduced heat of hydration. Several types of fly ash are produced depending on the coal and
coal combustion process. It is a pozzolanic material and has been classified into two classes.
Fly ash is one of the residues generated in combustion, and comprises the fine particles that
rise with the flue gases
This paper focuses on the experimental investigation to study percentage replacement of fly
ash for cement content in the concrete and deciding the water binder ration to achieve the
intrinsic properties such as compressive strength, split tensile strength and flexural strength for
a mix design by casting number of cubes, cylinders and prisms to ascertain that the strength
characteristics and then to understand the load deflection characteristics, model beams were
cast and tested after 28 days of curing.
A replacement of 30% of fly ash to the weight of the cement is optimum to achieve required
strength and ascertain that the durability properties can also adequately achieved
