AB In accordance with the European politics of reducing the amount of polymers and plastics wastes,the inclusion of compounds such as roof wastes as recycled and reusable materials to replacevariable amounts of aggregates is interesting in the production of new construction materials dueto their physical and chemical behaviour.Prefabricated mortar blocks have made with Portland cement, sand, water and grinded roofpolyurethane based wastes from the automobile industry that replace in different amounts part orall of the aggregates. To try to avoid the mechanical resistance limitation due to the use of roofwastes, the chemical properties of the binders have been modified with non-ionic surfactants thatimprove the effect on the hydration of the clinker. This variation produces an important change inthe mechanical resistance to achieve recycled structural materials with a density between 18.7%and 62.7% lower compared to conventional lightweight mortars. In addition, these surfactantsimprove other properties including workability, compaction of the matrix, prevent the disintegration of the particles and help to improve the mechanical properties and durability against fireto reinforce the materials.These eco-mortars have a good behaviour against temperature of the final envelope, measuredin terms of non-combustibility test. With these results, the use of roof wastes can be consider as asustainable alternative to the materials currently used and then with them we can be able tocontribute to a more ecological business model in the building sector.
