Abstract	The development of technologies for environmental protection contributes to save and preserve natural resources. Recently, both government and private sectors have accepted the view that rational utilization of non-renewable resources must be achieved. Historically, concrete industry relies heavily on the use of natural aggregates and Portland cement. Abundance of natural fine and coarse aggregates, located close to major cities, prescription specifications, and large production and inexpensive transport have contributed to this practice. On the other hand, related with limited waste disposal sites, an ecologically sustainable and responsible attitude is being adopted with respect to waste minimisation and utilisation of alternative materials in construction, to improve sustainability through energy efficiency, reducing CO$_{2}$ emissions, the cost of building and life-cycle maintenance. This paper presents the use of some natural raw materials and industrial by-products as substitution materials towards concrete sustainability. The reported materials are used as cement or aggregate replacement and are environmentally safe (non hazardous) and stable.
