Chopped Basalt Fiber-Reinforced High-Performance Concrete: An Experimental and Analytical Study

Basalt fiber (BF) is an environmentally friendly type of that has attracted the attention researchers in recent years due to its excellent performance concrete constructions. This current research was conducted investigate effect chopped basalt on workability, compressive strength, and impact resistance high-performance (HPC). Three various lengths (3, 12, 18 mm) six volume fractions (0%, 0.075%, 0.15%, 0.3%, 0.45%, 0.6% by volume) BF were used producing sixteen HPC mixes. strength measured for each mix. Scanning electron microscopy (SEM) analysis also selected mixes closely effects applied variables through microstructural scale. An empirical model developed study relationship between energy BF-reinforced HPC. The results show adding improves resistance. Compared with control concrete, reinforced 3 mm, 12 mm increased 12.2%, 15.1%, 17.5%, respectively. a dosage 8 kg/m3 all BF. SEM observations revealed accumulated pores surface attached cement which improved microstructure interfacial transition zone (ITZ), further enhanced ductility
