Construction and demolition wastes are produced every day around the world.
Thus the idea of using recycled concrete aggregate in new concrete production appears to be an effective utilization of concrete waste.
This paper presents the results of an experimental study to evaluate the effects of recycled concrete aggregate (RCA) percentages under different curing conditions.
The percentages of recycled coarse aggregate to dolomite were (0:100%, 25:75%, 50:50%, 100:0%) respectively.
The concrete properties which were studied were the mechanical properties (compressive and splitting strength) and mass transport properties (ISAT and sorptivity).
The concrete specimens were exposed to three different curing conditions, moist (standard), open-air, and painted specimens using the substance (Curassol 1).
The coarse recycled concrete aggregates were obtained by crushing a laboratory produced primary concrete at age of 28 days.
The results showed that curing using paint material was the most efficient method of curing at all ages and percentages of recycling except at 100% recycling, where the maximum value of both compressive and tensile strengths was obtained using water curing.
Also, in moist curing, full replacement of coarse aggregates gave the highest compressive strength at age of 28 days.
In all cases of recycled aggregate ratios, curing using water caused a decrease in the concrete permeability.
