Wastes Used for Obtaining Sustainable Building Materials

Advanced strategies have recently been investigated in order to decrease the environmental pollution, the danger of depleting raw material stocks, and increasing pollution following the release of significant volumes of CO2, resulted by the manufacturing of ordinary cement. The total or partial substitution of cement with a variety of wastes or by-products, from other industrial sectors, is one method of utilizing its to create new building materials. The following wastes can be employed as raw materials in the formulation of advanced materials based on their qualities and chemical content: fly ash, silica fume, bottom ash, phosphogypsum, rice husk ash, red mud, slag, oil fuel ash, etc. For design the building materials with the requirement properties, wastes and by-products utilized as raw materials are activated with different reagents. In this paper wastes from burning processes and few industrial wastes are presented, with refer to most important properties for obtaining the proper building materials
