Effects of Using Fine Quarry Waste as Cement Replacement Material on the Compressive Strength of the Mixture of Interlocking Block

Abstract:

The compressive strength of the sand-cement interlocking block mixtures were investigated by the method adapt from ASTM C 109. The cementitious to sand ratio of all mixtures were set at 1:2.75. Amount of water in the mixtures were 8% by weight of the solid as determined from optimum water content according to the compaction test (ASTM D698). In the mixtures, cement was replaced by fine quarry waste at the rate of 0, 10, 20, 30, 40 and 50% by weight of the binder. The results show that the average density of the mixture is 2.30 ton/m³ while increasing percentage of fine quarry wastes to replace cement decreases the compressive strength of the mixture at all tested ages (i.e. 1, 3, 7, 14, 28, 56 and 90 days). Moreover, the compressive strength ratio, the proposed parameter in this paper, shows a close relationship between percentages replacement of fine quarry wastes and compressive strength at later age.
