Fire behaviour of ecological soil-cement blocks with waste incorporation: Experimental and numerical analysis

摘要

The main goal of this study is to assess the behaviour of soil-cement blocks with incorporation of organic wastes. The problem of waste accumulation exists worldwide and has become a concern in today's society, leading to enormous environmental damage. One of the possibilities for reducing their environmental impact is the reuse of these wastes in new materials. However, incorporating waste changes the mechanical, physical and thermal properties of the new material. In order to evaluate the potential use of waste in blocks composition, laboratory tests were conducted and the results were analysed. This article presents the fire behaviour of ecological soil-cement blocks with waste incorporation. Therefore, an experimental programme was performed using samples of wall panel with soil-cement blocks. The wall specimen under fire conditions was also analysed by a non-linear transient finite element numerical model, in time and temperature domains, and the numerical and experimental temperature fields were compared.
