摘要：Concrete is a composite material which is comprises of blue metal and sand which are bonded together
with a fluid cement which hardens over time. Concrete has been used since ancient times to build massive structures.
Various researches have been carried out for a long time looking for replacement materials for the constituents of
concrete to improve various properties such as strength, permeability, etc. Researchers have also taken a path to reduce
the cost of concrete production by use of various locally available replacement materials. The concrete industry is on
the lookout for replacement materials constantly due to various ill effects in the current materials. In this experimental
investigation natural sand is partially replaced by foundry sand. This material has been used as replacement in 20, 30 &
40% initially. We are also adding 3% of coconut fibre by the weight of cement in each mix .This research describes
experimental studies on the use of coconut fibre to enhance tensile property in concrete. There are very less research
papers that indicate the effects of using these materials as individual replacement materials in concrete. There is no
evidence of these materials being used together as replacement materials in concrete which led to the ideology of
experimenting the usage of combination of replacement materials in concrete. The experimental investigation were
carried out using M20 grade concrete. The replacement material was used to replace the conventional elements of
concrete in the percentages 20, 30& 40.The combinations of these percentages have been carried out to keenly to note
the results and strength variations.
