The use of basalt rebar significantly increases the strength and durability of concrete structures. Basalt rebar is a type of reinforcement made from basalt rock and is used as an alternative to traditional steel reinforcement. It has been found to have several advantages over steel rebar, making it a popular choice in construction projects.

To study the frictional properties of bare rock surfaces, experiments were designed in unconfined single-direct shear configuration, in which two blocks were juxtaposed to simulate a fault surface (Fig. 1 c).In this experimental geometry, the sliding area of 16 cm 2 was also kept constant during the test. Due to limited tensile strength of the unconfined basalt …
Incorporating specific fiber proportions into RAC has been proven to effectively enhance its fracture properties [34]. The main commonly used fibers are steel fiber (SF), carbon fiber (CF), polypropylene fiber (PPF), glass fiber (GF), and basalt fiber (BF) [35], [36], [37]. The use of SF in RAC improves the fracture properties of RAC [38].
