Abstract
This paper reports on the properties of a new range of structural and lightweight mortars, including a low fraction of soluble nonionic surfactant, manufactured with different substitution rates of sand by polyurethane foam wastes. The characterization consists in substituting sand by polyurethane wastes and adding low fractions of nonionic surfactants with respect to the amount of cement. As characterized by the evolution of the mechanical strengths and porosity, the properties of the hardened mortars can vary significantly according to the chemical structure – hydrophilic–lipophilic balance value – of the nonionic surfactant. This new range of materials containing polymer wastes complies with the principle of sustainable development and contributes to a greener business model within the building sector.
