Abstract

The purpose of this study was to develop new environment clean and economic efficient composites of concrete and ceramics construction materials from hazardous industrial and municipal wastes. All the raw and the developed materials were analyzed by XRF, XRD, DTA and TGA, SEM, AAS, and LAMMA methods. The ceramics showed very high axial and flexural resistance and low values of linear shrinkage, water absorption, and bulk density. The solubility and leaching of heavy metals from the developed composites with high content (till 75 -100%) of industrial wastes were far below Brazilian standards, which makes them eco-friendly materials. Such properties allow the use of the industrial and municipal wastes for the production of concrete bricks, facing tiles, roof tiles, blocks, and bricks with high economic and ecologic efficiency.

Keywords:
hazardous industrial and municipal wastes, raw construction materials, amorphous new formations, high mechanical properties, strong chemical bonding, heavy metals leaching/solubility, environment-friendly ceramic materials, economic efficiency
