Study on Flexural Behaviour of Reinforced Cement Concrete using Pet Wires

Concrete is the most widely used construction material. Despite it is versatility in construction, it is known to have several limitations. It is weak in tension, has limited ductility and little resistance to cracking. The fibres act as micro crack arrester in cement composites. Many commercial fibres like steel, carbon, glass etc. are used as an addition or a replacement in the concrete to increase the strength. But use of steel and carbon fibres in concrete may be quite expensive when used in a large scale. So usage of PET fibre in concrete will enhance to reduce the cost as well as the environmental degradation. PET is unreinforced, semi-crystalline thermo-plastic polyester derived from polyester family. PET fibre can be used in concrete to improve its ductile parameters. This study presents the experimental investigation of PET fibre as a building material in concrete. PET fibres are added into the concrete in the percentages of 0.0 to 1.5% by weight of specimen at the increment of 0.5%. This study includes the strength characteristics of PET fibre concrete and investigate the mechanical properties such as compressive strength, Split tensile strength and Flexural strength.
