Avaliação das propriedades de misturas para tijolos ecológicos produzidas com resíduos de construção e demolição

Abstract

The construction industry has been consuming more and more natural resources. The Growth Acceleration Program (P AC) 1, followed by P AC 2 and P AC 3, is driving the increase in construction projects. The aforementioned scenario results in the generation of construction and demolition waste (CDW). In this scenario, the use of CDW in producing ecological bricks can be a viable solution to reduce the impacts of the construction production chain, mainly due to the consumption of waste, which would previously have to be discarded. Another important aspect is that soil-cement bricks do not need to be fired, unlike the most commonly used bricks today , which are made of ceramic material. Based on the above, the general objective of this work is to evaluate mixtures for the production of soil-cement bricks with different percentages of CDW as a partial replacement for soil. T o this end, the materials used were initially characterized and, subsequently , the mixtures were evaluated for compressive strength and absorption by immersion. The results showed that the incorporation of RCD into ecological bricks is a promising alternative for the management of construction waste, providing a more sustainable destination for these materials and reducing the extraction of natural resources.
