Impact of Chopped Basalt Fiber on Mechanical properties of Concrete: An Experimental Investigation

Fibre reinforced concrete (FRC) is well known for its high flexural strength, ductility and sufficient durability. This research aim to develop high strength Fibre reinforced concrete along with ductility and durability. In this present study, effect of the different percentage volume fraction of Chopped Basalt Fibres of length 24 mm on the mechanical properties of FRC were analyzed. Cubes, cylinder and prisms are prepared with 0%, 0.5%, 1.0% and 2.0% of volume fraction of basalt fibres. The results shows that adding of basalt fibres significantly improves the tensile strength, Flexural strength and compressive strength of the concrete but as the BF content increase the slump value decrease. compared with conventional concrete, the compressive strength, splitting tensile strength and Flexural Strength of concrete reinforced with basalt fibre increases by 2.55% – 6.24%, 5.58%-17.58%, 6.79% – 23.28% respectively. From the results of the experiments, it is concluded that an optimum dosage of basalt fibre for Compressive strength is 1.5%, for Splitting tensile and Flexural strength is 1.0%.
