Results of Felixkala and Ilangovana et al. also clearly show that granite powder as a partial sand replacement has beneficial effects of the mechanical properties of high performance concrete [8], [9]. According to Ho et al. [6] in normal concrete, the introduction of quarry dust to mixes must be limited due to its high fineness.
