Study on Mechanical Properties and Crack Evolution of Basalt Fiber-Reinforced Desert Sand High-Strength Concrete Based on DIC
This study investigates the strength development, crack evolution and toughening mechanism of basalt fiber-reinforced desert sand high-strength concrete. An L9(33) orthogonal design was first used to optimize the reference mixture, after which basalt fibers with volume fractions of 0, 0.3%, 0.4% and 0.5% were incorpora...
