Proper sand grading improves mass concrete
Report on tests of compressive strength, resistance to freezing and thawing, and drying shrinkage; good durability in freezing and thawing can be obtained with fineness modulus between 2.50 and 2.90; with increased air content, fineness modulus range can be increased to extend from 1.58 to 3.24; air entraining admixture requirement increased greatly as fineness modulus of sand decreased; water ratio also tended to increase with decreasing fineness modulus.
