Experimental Investigations on Basalt Fibre-Reinforced Concrete
Abstract Fibres are used in concrete to improve its structural integrity. Nowadays, among all basalt fibres, an inert mineral fibre is gaining more importance due to its exceptional properties, which include resistance to corrosion and low thermal conductivity. It also improves tensile strength, flexural strength and toughness of concrete. It can be used to extend the life of important concrete structures such as nuclear power plants, highways, bridges and runways. Basalt fibre in concrete is still an exploratory area due to limited studies. Therefore, a systematic study on basalt fibre-reinforced concrete was carried out with percentage volume fraction of fibre 0.50 (13.0 kg/m3), 0.75 (19.5 kg/m3) and 1.00 (26.0 kg/m3). The increase in compressive, splitting tensile and flexural strength is in the order of 26.79, 42.71 and 44.06%, respectively, for 0.50% dosage of basalt fibre as compared to control concrete. In addition, basalt fibre is found to be amorphous and hydrophilic in nature.
