Abstract

In this study, the effects of fine recycled concrete and glass aggregate on mechanical and durability performance of concrete were investigated. The waste concrete and glass were crushed, sieved and re-mixed to fulfill the same gradation as the available 0-4 mm crushed limestone aggregate size fraction. The recycled aggregates were substituted for fine aggregate as 0, 15, 30, 45 and 60 % by weight. 28-day mechanical and durability performance of the mixtures were determined. The maximum reduction in strength was observed in the specimens containing 60 % recycled glass aggregate. In addition, increasing the recycled concrete aggregate content caused decrease in UPV value and increase in water absorption, depth of penetration of water under pressure, chloride-ion penetration and water sorptivity of the concrete mixture. However, in recycled glass aggregate-containing mixture, UPV value increased and transport properties were improved with the increasing recycled glass aggregate content.
