process of obtaining and compositing recycled lightweight aggregate for alkali-activated mortars and concretes and alkali-activated mortar compositions

摘要

process of obtaining and compositing recycled lightweight aggregate for alkali-activated mortars and concretes and alkali-activated mortar compositions. The present invention belongs to the technological sector of the non-structural elements construction industry and relates more specifically to a novel composition of recycled polyurethane (pu) coated lightweight eVA waste for mortar and concrete. alkali-activated for non-structural elements, mortars and alkali-activated concretes and their obtaining processes. The new lightweight aggregate composition aims to use footwear industry waste as aggregate, in order to reduce the amount of waste material sent to industrial landfills, thereby reducing the consumption of mineral aggregate (sand), contributing to the reduction of the anthropic effect. . In addition, the nonstructural elements that will be produced from the processes proposed in the present invention will be lighter than those available on the market, which will require smaller structures.
