Fomulation of alkali-activated materials based on Quebec industrial waste by rheological, mechanical and durability analysis in different climates

Portland cement employed in conventional concretes is responsible for 5-7% of the world’s carbon dioxide. Alkali-activated binders appears as one of the promising alternative materials to substitute the use of Portland cement in concrete. Despite this, there are still technical obstacles to be overcome for industrial use. The main gaps include the production of alkali-activated concretes with mechanical and rheological performance suitable for current construction technology application (workability) and the production of durable materials especially in a variety of more extreme environments. Therefore, this project aims at the development of alkali-activated materials in Quebec, with local residual materials, which can be applied in concretes, that are efficient and durable in the Canadian climate. For this, the research will be based on rheological, mechanical and durability behaviors analyze of the materials. Durability tests will focus in evaluate resistance to chemical attack, to freeze-thaw cycles and analysis of pore structures.
