Abstract:To contribute to the recycled aggregate concrete study, an experimental test was made by substituting the natural aggregates for recycled aggregates of concrete, of mortar and of red ceramic, which are the three main ingredients of Brazilian construction and demolition waste. Besides the aggregate types, the water/cement ratio (w/c) was also changed from 0.4 to 0.8, fixing the amount of pre soaking water of the recycled aggregates. The concrete’s module of deformation was determined at 28-days age, using the Brazilian Standard ABNT NBR 8522/03, in cylindrical specimens. The results show that substituting the natural aggregates for the recycled aggregates reduces the module of deformation, and that the coarse red ceramic recycled aggregate and the fine concrete recycled aggregate were the ones that exerted the greatest and the smallest influence, respectively, on the concrete’s module of deformation.
