The influence of grading and maximum size of natural quartz sands on the workability of mortars was studied. Both the grading and fineness modulus were found to affect the water requirement. Graphs are presented for the effect of grading, specific surface of sand and cement content on water requirement in mortars made with sands of maximum size 2.4 and 1.2 mm, respectively, and grading zones are proposed for these sands. Optimal sand composition was also found for fine sand with maximum size 0.6 mm.
