Abstract: In the Netherlands for already about two decades, there is a strong interest in reuse of concrete and masonry aggregates in new concrete structures. According to the current Dutch Concrete Code it is allowed to replace 20% of coarse dense aggregates by mixed recycled aggregates (combination of concrete and masonry aggregates). Furthermore according to a CUR Recommendation [1] replacement of 100% of the coarse aggregates is allowed in concrete walls for structures in safety class 1 and 2 (no or small risk for human life).
Before further extending the possibilities for the use of concrete and masonry aggregates in concrete, it was decided to first investigate the behaviour of mixed recycled aggregate with respect to several phenomena. As part of an extensive research programme TNO Building and Construction Research performed tensile tests on cast-in-place and postinstalled anchors. The anchors were loaded in tension till failure. For the base material gravel concrete (reference), mixed recycled aggregate concrete and masonry concrete (100% masonry aggregates for the coarse aggregates) was used. In the paper the experiments and the obtained results are presented.
