چکیده مقاله
In this study the effects of recycled glass and recycled concrete fine aggregates on the compressive strength, water absorption, chloride ion penetration, freeze thaw and sulfate resistance as well as ASR expansion of mortar mixtures were investigated comparatively For this purpose, 9 different mortar mixtures were prepared by replacing 25, 50, 75 and 100 wt% of crushed limestone fine aggregate with recycled aggregates Test results demonstrated that, compared to the control mixture, compressive strength of the mortar mixture decreased with increasing the recycled aggregate replacement level The transport properties of recycled concrete aggregate containing mixture were lower than those of the other two series Frost resistance of mortar mixture improved by using both of the recycled aggregates ASR expansion increased with increasing recycled glass aggregate replacement level Mortar mixtures containing more than 50% recycled concrete aggregate showed higher sulfate resistance than the control mixture This was attributed to the accumulation of ettringite in pores of the RC aggregate resulting in lower expansion
