The effect of basalt fiber addition on cement concrete: A review focused on basalt fiber shotcrete

Basalt fiber, as a natural silicate has excellent engineering performance in high and low temperature resistance, fracture strength, toughness, shear elastic modulus nature. Shotcrete was widely used tunnel lining, slope support, coal mine roadway other projects. With the continuous development of shotcrete technology, scholars found that adding fiber to would greatly improve shotcrete. Compared with traditional plain steel shotcrete, incorporated basalt can dramatically bending toughness durability, therefore effectively improving concrete structure, such lining support. This paper summarized discussed mechanical properties, early age performance, durability practical applications reinforced focus on (BFSC). Meanwhile, it focused improvement enhancement mechanisms mineral admixture into assessed deficiencies existing current research. Eventually, suggestions prospects for future BFSC related research were proposed.
