Up to now, only a few papers investigated the use of precast elements produced with recycled aggregates. Nor is there any publication that pertains to concrete that has been compacted by a vibrating press. This article reports on such investigation and the related findings.

A concrete was envisaged that would allow for recycled aggregates as an input material, rather than just an additive or material put into the process at a later stage. The project generally aimed to achieve a high ratio of recycled materials. This concrete should include a higher percentage of recycled materials than established in previous investigations into the behavior of other types of concrete. During the research, a no-slump concrete was “sought” that would tolerate the properties of the recycled aggregates from Majorca.

The production of precast elements from vibrated concrete was...
