K. Rüdiger Reischuknt of discarded residue in the environment; in addition, it is technically and economically viable. This research aims at producing artificial stone from 85 wt% of granite waste incorporated in 15 wt% of vegetable polyurethane to be used in the construction industry. Initially, the best particle siz

K. Rüdiger Reischukn, and apparent porosity were, 2.24 g/cm., 0.19%, 0.42%, respectively. The flexural strength obtained by the rupture stress was 18 MPa. The results in tests are within the standard expected range, and show the good performance of the artificial stone.
