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%).
