oa Investigation of the mechanical and chemical properties of aluminum waste incorporated concrete

Portland cement-based products (primarily concretes) are the world's most commonly used building materials, and due to its huge production world-wide, especially in developing countries like Qatar, the Portland cement industry is faced economic, energy and environmental problems, such as 7% of total world-wide CO2 emissions. For sustainable development, within the scientific community, major international concern over how to reduce CO2 emissions has given rise to a growing interest in the development of materials and technologies able to reduce the impact of Portland cement. One of the possible alternative ways of sustainable development in construction industry is to replace a large percentage of cement with other materials like industrial wastes, slag and fly ash which reduce the environmental impact of manufacturing an equivalent amount of cement and allow industry wastes to be safely recycled into a permanent structure rather than into a landfill site. It is the objective of this project is to investigate the mechanical and chemical behavior of new concrete type obtained by adding aluminum slag which is an impure aluminum mixture that results from metals melting and mixing with flux. The main advantage of this type of concrete over the conventional ones is the reduction in the quantity of raw materials.
