Performance of basalt fibre mixed concrete
Abstract
In this research, the mechanical properties of smart concrete made of chopped basalt fibre were investigated. Two different types of basalt fibres (bundles and filaments) were used.The basalt fibre specimens were cast using basalt fibres of varying length (12 mm, 36 mm, and 50 mm) and varying fibre dosage (4 kg/m 3 , 8 kg/m 3 , and 12 kg/m 3 ). The results indicated that the 50 mm basalt bundled fibre at 8 kg/m 3 was the optimum fibre length and fibre volume for basalt bundled fibres. It provided the optimum increase in flexural strength, compressive strength, and split tensile strength when compared with plain concrete. Similarly, the 36 mm basalt filament at 8 kg/m 3 was the optimum fibre length and fibre volume for basalt filaments. It provided the optimum increase in flexural strength,compressive strength, and split tensile strength when compared with plain concrete.
