Experimental Study on Concrete with Straight and Crimped Plastic Fibres

Concrete is the most broadly used construction material in the world due to its compressive strength, extended service life, and low cost. This experimental program seeks to optimize the benefits of using straight and crimped plastic fibres, from waste polyethylene terephthalate (PET) bottles. As plastic is non-biodegradable, its disposal become a problem. To prevent this, the fibres from waste bottles were added in different percentages in the M30 grade concrete. The plastic bottles were shredded into fibres of specific size and shape. An experimental set up was carried out in the laboratory and the test were observed. The plastic fibres were added from 0 % to 1.5 % for different aspect ratios. The various tests were conducted and the results obtained are compared with the control specimen and the results are plotted in the form of graph.
