Through quasistatic loading experiment and split Hopkinson pressure bar …

Elshafie [29] reported that the most significant improvement in the mechanical properties of BFRC was achieved when the length of basalt fibers ranged from 12 to 24 mm, and their fraction was 0.1–0.5 vol %.Thus, we chose ordinary concrete with strength grade C35 as the base, maintained the length of basalt fibers at 18 mm, and …

This paper looked into the compression strength of basalt fiber reinforced concrete when it bears expanded clay as aggregate and when it bears the usual gravel as aggregate. One thing to note is that the weight of both BFRC specimens vary as, the BFRC with expanded clay showed much lighter weight than that of BFRC with gravel.

The RF prediction results show that with the increase of confining pressure, the elastic modulus of BFRC specimens also increases correspondingly, and the …

For the basalt after thermal treatment at 1000 °C, the radial tensile stress on the basalt exceeds the tensile strength of the specimens under the effect of uniaxial compression, which triggers a certain number of tensile cracks that are parallel to the loading direction and quasi-parallel cracks. Tensile failure (splitting failure) then occurred.

The performance of basalt fibers in concrete under quasi-compression strength has been reported by Fu et al., 64 The addition of 0.1% of basalt fibers had better compressive strength against other fibers used in the research. Since the basalt fibers had tendency to mix with water, it resulted in greater bonding strength.

In this study, the basalt rock extracted from the Kalgoorlie region of Western Australia is intensively studied on its compressive properties under both static and dynamic loads covering strain rate between 2.22 × 10 -6 /s to 408/s. The ultimate compressive strength and corresponding failure strain are quantified.

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.

The compression test results of basalt FRP bars and glass FRP bars are shown in Table 4. Compression test performed under various lengths of the specimens, the results show that glass FRP Bars are having better compression strength under the lengths i.e. 50 mm, 100 mm, 150 mm and 200 mm when compared with basalt FRP bars.

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.

Fibers improve concrete's strength; the high ductility of flexible fibers might reduce the material's resistance to fracture [5]. Basalt fiber (BF) has a significant modulus of elasticity, providing exceptional stiffness, structural integrity, and durability [6], [7]. Due to its excellent mix of qualities, BF is recognized as a highly adaptable ...

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 …
