Researchers from the University of Burgos (UBU) have developed a fire-resistant cement precast lightened with industrial waste of polymeric origin, from recycled vehicle roofs, made in the form of a block for the construction of walls or a similar structure.
New and innovative aspects
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 added value 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 be able to apply the current legislation.
Main advantages of its use
The characteristics and nature of construction materials, based on cement, make it possible to enhance foams that come from polyurethane insulating panels with remains of other materials (adhesives, metal oxides, remains of paint and / or plasters, etc.). The cement is of the Portland Cement type with a mass composition of 95-100% clinker and 0-5% minor components. 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, but at the same time, with a low density compared to conventional light mortars. This precast cement lightened with polymer matrix residues provides improvements in the physical characteristics of the precast, with weight reductions of up to 70%.
Potential applications of the tank are as follow:
Intellectual property status
Protected by Utility Model U202131039
Current development status
Developed exclusively in the laboratory and validated for industrialization.
Desired business relationship
Commercial Agreement, License Agreement, Technical Cooperation: further development; Technical Cooperation: testing new applications; Technical Cooperation: adaptation to specific needs.
The aim of the The Technology Transfer Office (TTO) of the Univesidad de Burgos is to promote Innovation technology through the reseach results transfer and the conexions between the University and the new needs and requirements of the society - we are the link between the University and the Industry.
