The uniaxial compressive strength of a rock under static loading often decreases with an increasing temperature at which the rock has been heat-treated before strength testing. This conclusion is drawn from a great number of experiments [1,2,4,8,9,11,17–19].The higher the temperature is, the lower the strength. Some results for uniaxial compressive strength σ c and tensile strength σ t ...
The average compressive strength enhancement of 2L- and 4L-BFRP-CFRC is 2.15 and 3.03 for the small-size specimens, and 1.22 and 1.63 for the large-size specimens, respectively. As anticipated, the lateral confinement stress increases with the tube thicknesses.

Values of tensile and cohesive strength for the basaltic rock mass are approximately one to two orders of magnitude lower than corresponding values for intact basalt. Temperatures comparable to those at the Venus surface may slightly increase the deformation modulus but decrease the compressive strength .
Beside the diametral test, the axial test and the irregular lump test have also been proposed (see Figures 2b and 2c). Strength anisotropy can also be assessed by using the point load index as suggested by Broch (1983) who proposed an anisotropy index Ia equal to 2.3 Uniaxial Tension Direct measurements of tensile strength are di fficult.
[14, 30–37]). In [37] a comparison of axial tensile and compressive strength of car-bon fibres was done. Tong et al [38] have used the nanoindentation technique for the measurement of compressive strength of basalt fibres. Together, these meth-ods have provided much useful information for comparisons of fiber compressive properties.
Based on the test results, the optimal BF volume fractions for cube compressive, axial compressive, splitting tensile strength and elastic modulus of RAC were 0.1%, 0.2%, 0.2% and 0.2% respectively. Moreover, the optimal fractions were refined by using the BPNNs as 0.1%, 0.15%, 0.1% and 0.2% respectively.

Compressive strength or compression strength is the capacity of a material or structure to withstand loads tending to reduce size, as opposed to which withstands loads tending to elongate. In other words, compressive strength resists being pushed together, whereas tensile strength resists tension (being pulled apart). In the study of strength of materials, tensile strength, compressive ...
Axial compression test was conducted to investigate the effect of confinement on plain concrete cylinders by wrapping polyethylene naphthalate fiber reinforced polymer (PEN FRP) with large rupture strain (LRS) capacity. To draw comparison on the confinement effect by PEN FRP wrapping, the confining effect by basalt FRP (BFRP) wrapping was also investigated.
