Shrinkage of concrete with replacement of aggregate with recycled concrete aggregate
In this paper the authors present the experimental analysis of samples of concrete where portion of the natural aggregate were replaced with recycled aggregate originating from concrete (RCA). Experimental analysis to obtain the shrinkage properties (basic and dried) of the concrete containing recycled concrete aggregate (CRCA) was performed. The percentages of replacement of natural aggregate with RCA were 0 %, 15 %, 30 %, 60 % and 100 % with test conditions of 50 % RH and 20 deg C. The results of these trials are compared with reference concrete tests, at an age of 270 days. The results demonstrated an increase in the shrinkage of the CRCA that is proportional to the amount of RCA used as a replacement for the natural aggregate. When compared to the reference concrete, the drying shrinkage showing significant changes; however, their evolution over time is similar to Standard concrete.
