Gonçalves et al. [29] and Shen, et al. [30] claimed that higher fine content in quarry dust increased water absorption rate which in turn increased water demand for mortar mix. Therefore, water to cement ratio was increased for concrete with quarry dust to sustain similar workability of conventional concrete [31,32].
