Three types of cements and three types of fine aggregates, viz seashore sand, crushed stone and a blend of the two were utilized for this study. The water-to-cement ratio by weight ranged from 0.40 to 0.50. All mixes were made at a slump of 10-cm (4-in.) and air content of 4 percent. The blended cement concrete with fly ash showed the lowest shrinkage among the three cement concretes. The creep tests showed similar results. Good workability, high strength, low shrinkage and creep could be achieved using fly ash concretes.
