Methods for determining mean particle size (fineness modulus), particle size distribution, particle shape, and solid content of natural sands are presented. It is shown how these properties relate to the water requirements of mortars and concretes proportioned by a recognizedsystem. Using 3/4-in. and 1-in. crushed stone as coarse aggregate and proportioning by ACI’s rccommended practice for proportioning of concrete mixes, at a constant water-cement ratio, it was found that water requirements to produce concrete of a given slump could be predicted to 95 percent accuracy for 95 percent of the sands used in the experiments.
