Abstract:
This paper presents the main results of experiments conducted to ascertain the influence of different curing conditions on the durability of recycled aggregate concrete (RAC) made with coarse crushed concrete. Four different curing conditions representing a wide range of quality control production, ranging from uncontrolled outer environment conditions to standard defined temperature humidity curing conditions, were tested. The properties analyzed were shrinkage, water absorption by immersion and capillarity, carbonation, and chloride penetration. The general conclusion is that RAC is affected by curing conditions in much the same way as conventional concrete (CC).
