The effect of BF length on elasticity modulus, as studied by Mehran et al. (Khan et al., 2022), is summarized in Fig. 11. The results of the tests revealed that adding basalt fibers reduced the modulus for all fiber lengths. Furthermore, an increase in the fibers length, led to a greater reduction in elastic modulus (up to about 20%).

Basalt is among the most used rocks as aggregate, ballast, ornamental stone and for other construction purposes. Therefore, the uniaxial compressive strength (UCS) and elasticity modulus (Ei) of intact rock are required to be known for several purposes. For this reason, the purpose of the present study is to develop various non-linear prediction Model s for UCS and …
It is a widely held view that elastic modulus is one of the important parameters reflecting the physical and mechanical properties of rock materials in rock mechanics and engineering (Brotons et al. 2014; Feng et al. 2019).Rock materials are quasi-brittle materials, which often suffer from dynamic load and temperature disturbance in energy, tunnel fire, and …
From Fig. 3(a), the modulus of elasticity of the matrix (geopolymer mix 3) can be determined which was found to be 1.9 GPa. As per the manufacturer data sheet, the modulus of elasticity of the dry basalt fibre is 95 GPa. Therefore, based on the rule of mixture the modulus of the GP-BFRP rebar should be 41 GPa.
