The uniaxial compressive strength test is used to determine the maximum value of stress obtained before failure. The determination of this parameter was carried out on specimens with dimensions 7 × 7 × 7 cm along two orthogonal directions (side A–side C), in order to identify possible anisotropies which were not identified by the test of water absorption by capillarity …

The residual strength is defined as the ratio between the compression strength of an impacted specimen and the compression strength of a non-impacted specimen [6], [28]. Fig. 7, Fig. 8 show the residual critical and failure stress for composites with different basalt/nylon fiber content at various impact levels.

This manuscript proposes a strength and ductility of reinforced concrete (RC) using basalt fibre-reinforced polymers (BFRP). The lightweight materials like fibre-reinforced polymers (FRPs) are providing superior structural performance and durability in reinforced concrete members over traditional materials. Due to its light weight property, they are proposed for building repair and ...

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.

Uniaxial compression tests were performed on different categories of weathering of three lithological units: Malanjkhand granite; Nagpur basalt; and Delhi quartzite, occurring in central and northern parts of India. The deformational behaviour is studied in terms of variation in tangent modulus (E t50) and initial modulus (E i) due to weathering.
