Análise de desempenho de tijolos ecológicos para emprego em construções habitacionais sustentáveis.

Abstract

This paper analyzes the performance of soil-cement bricks for the construction of residential buildings as a measure to reduce the environmental impacts of the construction industry. This product is popularly known as ecological brick due to its mixture of natural soil with a small portion of Portland cement in the production phase, with the possibility of using construction and demolition waste (CDW) and other types of waste in the mixture. Thus, this paper aims to analyze the performance level of soil-cement bricks, through wetting and drying cycles and compressive strength and water absorption tests. It was found that the type of soil, the mixing process of the inputs and the addition of hydrated lime directly interfere in the compressive strength and water absorption of ecological bricks.
