When considering the 10 % GP mix with the same w/c and w/b ratio as the 0.75 % basalt fiber mix, the compressive strength was less than that of the 0.75 % basalt fiber mix due to the impact of reduced cement ratio, as indicated by [47]. Furthermore, the increase in GP content, w/c ratio, and w/b ratio had a direct negative impact on …
