Effect of basalt fibre on the mechanical properties of M70 grade high performance concrete
The presented work reveals the strength properties of M70 grade high performance basalt fibre reinforced concrete (BFRCC) containing 0.2%, 0.3% and 0.4% basalt fibre content by volume of concrete. 10% Silica fume is admixed for attaining higher strengths as preferred. Compressive, split-tensile and...

| Summary: | The presented work reveals the strength properties of M70 grade high performance basalt fibre reinforced concrete (BFRCC) containing 0.2%, 0.3% and 0.4% basalt fibre content by volume of concrete. 10% Silica fume is admixed for attaining higher strengths as preferred. Compressive, split-tensile and flexural strengths are evaluated. The BFRCC microstructure is found to be improved due to enrichment of interfacial transition zone with chopped basalt fibres. It was found that different fibre lengths require different dosages to yield maximum effect on the properties of concrete. Stress- strain responses of M70 grade BFRSCC yields improved ultimate strain and strain at peak load indicating its energy dissipation capacity at fracture. |
