EXPERIMENTAL STUDY ON STRENGTH PROPERTIES OF CONCRETE WITH DIFFERENT ASPECT RATIOS OF BASALT FIBRE

Presence of fibre in concrete improves the physical properties as well as it acts as crack arresters. In this paper, an attempt is made to predict the impact of basalt fibre in the properties of M40 grade concrete. The influence of fibre length in the mechanical properties and the optimum range of fibre are also studied. The concrete specimens are cast and tested to determine the mechanical properties namely, compressive strength, split tensile strength and flexural strength. Three different length of basalt fibre such as 16 mm, 19 mm and 24 mm are used for the fibre content of 1%, 2% and 3% to the volume of the concrete. The variation of mechanical properties with the fibre length and optimum dosage of fibre content is found out experimentally. It was observed that higher fibre length showed increase in compressive strength, split tensile strength and flexural strength compared to plain concrete control specimen
