Modified Behaviour of Concrete by Replacing Fine Aggregates with Coal Fly Ash IJTSRD
The prime objective of the study was to evaluate the structural properties and potential of concrete containing coal fly ash that of concrete containing no coal fly ash of corresponding mix proportions and strength. The cubes were tested for the compressive strength and beams specimens were tested for flexural strength. Splitting tensile strength tests were conducted on cylinder specimens. The total numbers of 60 cubes, 40 beams specimens and 40 numbers of cylinders were tested for compressive strength, flexural strength and splitting tensile strength respectively at different ages to study the following aspect. The effect on unit weight of concrete after incorporating varying proportions of bottom ash. The effect of coal fly ash on workability C.F of fresh concrete. The effect on compressive, flexural and splitting tensile strength using bottom ash in varying percentages as a partial replacement of fine aggregates. Mix containing 30 and 40 bottom ash, at 90 days, attains the compressive strength equivalent to 109.13 and 105.17 of compressive strength of normal concrete at 28 days and attains flexural strength in the range of 112 116.3 at 90 days of flexural strength of normal concrete at 28 days.
