The inclusion of polyurethane wastes as recycled and reusable materials to replace variable amounts of aggregates is interesting in the production of new construction materials due to their final properties. In this research, the effects of waste polymer replace by sand (25%) and graphene oxide on mortars (0.5, 1, 1.5, 2, 2.5 y 3% with respect to the cement) have been investigated. To maintain and even improve the final properties, graphene oxide modify aspect as thermal conductivity and electrical properties, water behavior, mechanical properties and final contribution to fire.

摘要

The inclusion of polyurethane wastes as recycled and reusable materials to replace variable amounts of aggregates is interesting in the production of new construction materials due to their final properties. In this research, the effects of waste polymer replace by sand (25%) and graphene oxide on mortars (0.5, 1, 1.5, 2, 2.5 y 3% with respect to the cement) have been investigated. To maintain and even improve the final properties, graphene oxide modify aspect as thermal conductivity and electrical properties, water behavior, mechanical properties and final contribution to fire.
