Prefabricated of cement with fire resistant polymeric residues
ES1279026
Researchers from the University of Burgos (UBU) have developed a fire-resistant cement precast lightened with industrial waste of polymeric origin, made in the form of a block for the construction of walls or a similar structure. The novelty of the invention is based on the use of the waste from the roofs generated in the automobile industry, which is valued as raw material with benefit for its incorporation into the precast industry of the Construction Sector. The percentage of residue present in the final material depends on the required properties of the final product, obtaining properties in the hardened state sufficient to comply with the current legislation.
This alteration in the components of the precast cement object of the invention helps to maintain its mechanical strength, obtaining recycled materials with certainly structural capabilities, among them are: - This precast cement lightened with polymer matrix residues provides improvements in the physical characteristics of the precast, with weight reductions of up to 70%. - Greater thermal insulation of the final envelope, as well as a good behaviour against temperature and against fire (non-combustibility). - Recycling of waste for the construction of materials, moving from waste to new raw materials, with the reduction of the environmental impact that it entails. - Additives “à la carte”, polymeric in nature, which are added, maintained and even improved mechanical resistance within the necessary reference values required by European regulations.
