Experimental Analysis on Effect of Variable Aspects of Polypropylene Fibre on Reinforced Concrete Strength

Concrete is very weak in tension, has low ductility and very little resistance capacity to cracking. Fibres in a cementitious composite play a key role in reducing these issues. As a result, adding fibres to concrete enhances and strengthens its resilience, and these issues may be solved by using polypropylene-fibre. Replacement of cement and sand are the present issue in the current construction scenario, because of higher cost and environment pollutants. Polypropylene fibres are industrial by-product produced from manufacturing of plastics. Use of this plastic waste fibre does not just lower the cost of construction but also helps to reduce the impact on environment by consuming the material generally considered as waste product. Then, Initially the material tests such as time for the first and last settings, consistency, fineness modulus, compressive strength, specific gravity test for cement, sieve analysis, specific gravity, water absorption, silt content, bulk density, void ratio, test for coarse and fine aggregate are conducted and then, the compatibility of the Polypropylene fibre with the conventional material is tested using basic material testing. On the basis of properties & availability of polypropylene fibre (from various sources like plastic waste) in Bhopal region as well as in other places of India, a feasible way to use this waste product is evaluated without affecting strength characteristics of concrete. This dissertation represents the results of an experimental Analysis to investigate the impact on which Cement is partially replaced.
