Use of municipal waste to build ecological blocks

Abstract

The reduction of natural resources leads to the search for new alternatives, and the construction sector, as the largest consumer of these resources, if the conventional raw materials were substitute with recycled material it will causes a greatest positive impact. This work evaluates the mechanical and durability characteristics and resistance to high temperatures of soil-cement cylindrical specimens in three different compositions. A comparison between specimens with residues and specimens without residues (reference) is proposed, to investigate the possibility of being used as non-load bearing masonry walls. The characterization tests are based on Brazilian standards and compared to Spanish and German standards. For the high temperature analyses European standards and the ISO heating curve are used. After laboratory tests and comparative analysis between the specimens, was verified a drop in the performance of the specimens with residues, but the alternative of being used can not be discarded, since all are within the limits established by the standards used.
