The intense waste generation moved by the urban and industrial activity and the wasteful consumption of natural resources, encourage the development of new technologies for the utilization of wastes and its reuse in new industrial processes, which decreases the environmental pollution and the removal of virgin materials We work in the development of new materials and components from urban and industrial waste prepared by different techniques and with various applications, in the pursuit of offering alternatives to the construction of houses of social interest and reuse wastes. In this work we present partial results on the development of a composite material on the basis of recycled rubber from tires out of use (NFU) and polyethylene recovered, linked through the fusion of the plastic and the subsequent pressing of the material. This material has as main advantages the high resistance to flexion and the hard impact, low thermal conductivity, low water absorption and swelling null by immersion in water. These physical and mechanical properties were optimized by adjusting parameters of formulation and process, pointing to the development of a constructive component for covered of type roofing tile. Besides, we work in the aggregate of additives for improving the properties of the material to fulfill with norms for use in civil constructions In this article we present the partial results obtained in the physical and mechanical testing of the tiles, and the burning behavior of the component manufactured using this technology, and with the addition of flame retardants additives available in the market, to comply with the regulations to use of this type of housing components. We developed a constructive component suitable for use in civil constructions, with very good technical performance, both thermal conductivity and behavior against conditions of humidity. Besides, the component exhibits very good mechanical performance with high resistance to flexion and the hard impact. There was also a material with good behavior in front of the fire with the addition of additives flame retardants. As environmental advantages it is possible to take two types of waste in great abundance in all urban sites and with sustained availability at the time, providing solutions to the problem of waste with implementation of long-term. On the other hand we develop a component due to its high flexibility and resistance to impact hard is presented as a good constructive alternative for ceilings in areas affected by the fall of hail or by the risk of blowing up and deterioration by strong winds.
