Concreto leve ecológico - compósito de materiais com reduções de custos e impacto ambiental na construção civil

Abstract

This work addresses the application of lightweight concrete technology to the production of construction elements, such as prefabricated plates, fence panels and precast parts. The present invention of Lightweight Ecological Concrete - CLE, refers to a composite material resulting from the union of concrete with waste plastic polymers, which may be expanded polystyrene - EPS and polyethylene terephthalate - PET. The composite matrix is made up of materials characterized by containing in its mixture cement, aggregates and water, as basic elements, and an additive as an air-entraining agent. The composite filler consists of particulate plastic polymer residue with the function of light artificial aggregate. The ecological lightweight concrete of this invention is produced by replacing part of the fine particles of high-cost conventional Portland cement with low-cost recyclable plastic polymer waste, forming an economical, stable, non-contractile, lightweight product with mechanical and acoustic properties. fully satisfactory, composed from a chemical reaction between cement and the addition of these materials mentioned above. The definition of the ideal formula aimed to obtain a material with lower density and resistance to compression necessary to meet the technical standards of the Associação Brasileira de Normas Técnicas - ABNT. We also present in this work a theoretical foundation and a state of the art with what has been developed in the academic environment on lightweight concrete and with residues. Finally, we present a survey of the financial viability of CLE with its Canvas and the strategies used to jump the abyss in front of Rogers & Moore's Law of Adoption and Innovation. Finally, we present a survey of the financial viability of CLE with its Canvas. We attach at the end of this work the full text of the CLE patent and document of its deposit at the National Institute of Industrial Property - INPI.
