Abstract:This study presents the experimental results on properties of concrete with replacement of natural aggregate by recycled concrete aggregate (RCA). Experimental data on the creep behavior of concrete mixtures (basic and drying creep) was obtained. The replacement factor of natural aggregate by RCA were 0%, 15%,30%,60% and 10096, and the test conditions were 50% RH and 20°C. The results of these trials were used to provide a comparison with results of tests on the reference concrete, for ages up to 270 days. The creep coefficient data (instantaneous, basic and drying) presented, along with the maximum strain and the specific creep data. The results reveal considerable increase in creep when is increase replacement of natural aggregate with recycled concrete aggregate. The drying creep, especially shower more significant increase when compared to the reference concrete.
