In case of tensional stress of a uniform bar (stress-strain curve), the Hooke's law describes behaviour of a bar in the elastic region. The Young's modulus of elasticity is the elastic modulus for tensile and compressive stress in the linear elasticity regime of a uniaxial deformation and is usually assessed by tensile tests.

The use of basalt fibers promoted the elastic modulus of GC which showed the maximum peak load of about 1520 N. Finally, it was concluded that the use of BF improved the mechanical property of the specimens. b.

The average modulus of elasticity of GPC specimens decreased by 18 % (from 24.5 GPa to 20.0 GPa, as shown in Fig. 4 (a)), which indicates the clear effect of increasing BMF content from 0 % to 2 % on the modulus of elasticity. Meanwhile, the average moduli of elasticity of GPC specimens with 0 % and 1 % BMFs are 24.5 GPa and 23.8 GPa, respectively.

[1] Understanding the elastic behavior of basalt is important to seismically monitor volcanoes, subsea basalts, and carbon sequestration in basalt. We estimate the elastic properties of basalt samples from the Snake River Plain, Idaho, at ultrasonic (0.8 MHz) and seismic (2–300 Hz) frequencies.

It is also compared with elastic modulus calculated from different codal provisions. The static modulus is lower than the dynamic modulus. Adding basalt fiber improves the ductile characteristics of fine-grained concrete but retards on GGBS addition due to the dilution effect of cement on greater percentages of replacement.

The strength performance of basalt fibers improves, compared to glass fibers, with increasing temperature. The elastic modulus of basalt fibers is comparable to that of glass fibers, higher compared to E-type but lower compared to S-type. Elongation at break values is higher compared to carbon fiber but lower compared to glass one (Table 1.1).

When basalt fiber is well dispersed in concrete, it enhances the reinforcement effect of fiber-reinforced concrete [32], [33], [34]. Due to its high tensile strength and elastic modulus, basalt fiber plays an important role in bridging cracks and can be used for load-bearing components in building construction [35].
