Compression Behavior of Basalt Fiber
In this study, a composite material consists of basalt fiber-reinforced polymer (BFRP) tube-encased coconut fiber-reinforced concrete (CFRC) is developed. The 28-day compression strength of the plain concrete is about 15 MPa, which represents the low strength and poor-quality concrete widely existing in a large number of old buildings.

Mechanical Properties of Basalt Specimens Under Combined Compression
The peak strength and the elastic modulus of the basalt specimen in the uniaxial compression condition (θ = 0°) are defined as its UCS and Young's modulus, respectively. The rock failure pattern is recorded photographically, and rock post-failure behaviour is analyzed based on the complete stress–strain curve.
