Estudo da viabilidade da aplicação de resíduos de gesso em blocos de concreto para melhoria de propriedades termo-acústicas

Abstract

It has been looked for to improve the energy efficiency of buildings trying to follow the ideas of sustainable development. The construction industry is known as a strong generator of environmental impacts, so the sector is increasingly criticized because of the waste of raw materials. Gypsum is a material that has been highly used in construction, regarded as one of the most consumed construction materials in the world, thanks to its potential resistance, thermal and acoustic isolation, high durability, ease of installation and low cost. However, it is difficult to reuse it. We constructed prototypes with concrete blocks, one with and the other without the inclusion of gypsum waste inside the holes of the blocks. It was possible to compare both results, analyzing the thermal and the acoustic properties. The obtained results lead to an improvement of the thermal isolation and an indifference in the acoustic isolation. The conclusion achieved was that it’s viable to extinguish the solid waste trying to reach the desirable improvement.
