Enhancing the Strength Properties of the Concrete by Partial Replacement of Conventional River Sand with Plastic Waste Fibers

Urbanization is growing day by day with respect to time so the infrastructure also developing in chronologically ascending order, a major part of the construction infrastructure is concrete in the words, concrete is the most significant material in the construction industry, concrete is made of four basic ingredients water, cement, fine aggregate, and coarse aggregate from which coarse and fine aggregates are chemically inert materials they do not perform any chemical formation therefore the replacement of the fine aggregate can be possible with the chemically inert material which fulfill the mechanical strength criteria, in this research replacement of the fine aggregate is done with the waste plastic fibers to enhance the strength and durability without compromising the workability of the concrete, at replacement of 1.5% of fine aggregate with plastic waste fibers increase the compressive strength by 11.7% and flexure strength by 17%, but workability is reduced by 7 mm on the slumpcone workability test.
