The main objective of the project is to reduce the environmental impacts associated with concrete production by utilizing recycled aggregates and low-carbon footprint cement in an optimized way. The output of the project will be a verified technology for producing concrete mixtures with lower environmental impacts. Within the project, concrete mixtures with recycled aggregates and low carbon footprint cement, such as blended cement and blast furnace cement, will be optimized. Optimization will be carried out by experimentally verifying the properties of concrete mixtures, both mechanical and durability, with consideration for their planned structural use. At the same time, they will be optimized according to their environmental impacts, and evaluated by the Life Cycle Assessment (LCA).
