TO STUDY EFFECT OF RECYCLED CONCRETE WITH PLASTIC FIBRES ON STRENGTH PROPERTIES OF CONCRETE

Plastic fibre recycled concrete is a most broadly used solution for improving compressive, tensile and flexural strength of concrete. Reinforcement of concrete with fibre may improve the desired properties of concrete. The objective of this research is to investigate and compare the compressive, flexural and tensile strength of concrete for various mixture proportion of concrete. In this research, the effect of inclusion of normal and recycled aggregate with plastic fibre on the compressive, flexural and tensile properties of fibre reinforced concrete using M40 grade concrete was studied. Control and five concrete composites were cast using different fibre proportions of plain and recycled concrete with total volume plastic fibre fraction of 0.25%. The experimental work was divided into five group. Each group consists of 6 cubes (150 mm x 150 mm x 150 mm), 6 cylinder (300 mm x 150 mm dia.) and 6 beam (500 mm x 100 mm x 100 mm). Compressive strength, split tensile strength and flexural strength test were performed and results were extensively analyzed to identify performance synergy.
