THE PROPERTIES OF CONCRETE MADE WITH VERY FINE SAND

This article described the effects of sand fineness upon concrete properties. Fine quartzitic sand was used in mixes with two 20-5 mm coarse aggregates, tunstead limestone and croxden gravel. These were supplied in single sizes and combined for every mix to provide various gradings. Ordinary portland cement was used as the concrete. Sand contents of each mix were varied to study the effects upon the water required to maintain target slump and also to find the minimum practical sand content without adverse effect on the fresh properties of the concrete. Workability was assessed by the slump ve be and two point tests. Segregation, cohesion, harshness, bleeding and finish were assessed visually. After standard curing, compressive strength was determined using 100 and 150 mm cubes at 7, 28 and 91 days. Dynamic modulus of elasticity was determined on a 500 by 100 by 100 mm prism at the same ages and static modulus of elasticity using a 300 by 1500 mm cylinder at 28 days. Limited information on initial surface absorption and freeze thaw durability was also obtained. These tests showed that satifactory concrete of all types could be made with very fine marine dredged sand.
