Lightweight mortar obtained from recycled polyurethane foam
The aim of this paper is to present the results of an experimental study concerning the use of rigid polyurethane foam wastes applied to cementitious mixtures to produce lightweight concrete. The mortars were obtained by mixing cement with different amounts of polyurethane, aggregate and water. Dosage has been varied to replace aggregates with recycled polyurethane, while the amount of water has been optimized to obtain good workability. Rigid polyurethane has been triturated in a particle size between 0 mm and 4 mm before being used as a substitute of aggregate. Samples have been characterized and tested in both fresh and hardened state. The obtained results showed that the variation in the amount of polyurethane was affecting mortar properties, decreasing the mortar density and its mechanical properties and increasing its workability and permeability as well as the occluded air. These results confirm that mortars produced with recycled polyurethane are comparable to lightweight mortars made of traditional compounds.
