Abstract:
Recently, the tests concerning use of concrete with recycled aggregates (RAC) presented in different countries were focused on properties of material. Very few tests were done on structural reinforced-concrete members made of such kinds of concrete. Such tests are necessary because it is difficult to predict the influence of differences in particular properties on the overall behaviour of reinforced concrete members made of various mixtures of recycled aggregate concrete. The aim of the tests presented in the paper was to determine differences in behaviour of simple reinforced concrete members made of RAC in comparison with members made of ordinary concrete with natural aggregate. On the basis of former material tests four series of beams and four series of columns have been selected for tests. In general, the comparison of the results showed similar bearing capacity of members in the series, and significantly greater deformations of concrete in members with recycled aggregate concrete.
