Statistical Comparison of Properties of Manufactured Sand-to-Mortar Durability and Scaling Resistance

摘要

The results tests on rock aggregate and manufactured sand from Paleozoic carbonate rocks from quarries in SW Ontario were compared those of mortars containing the manufactured sand. The aggregate tests included petrographic analysis, water absorption and adsorption, linear expansion under various conditions, thermal expansion, insoluble residue content, micro-Deval abrasion loss, freeze-thaw loss, and rate of settlement of -0.075 mm. (-200) fraction. The mortar tests consisted of drying shrinkage, water absorption and adsorption, linear expansion under various conditions, thermal expansion, and scaling and freeze-thaw loss.
