Aluminum fluoride (AlF 3) is a chemical compound that can play a significant role in the manufacturing of cement and concrete, particularly under conditions that demand high resistance to chemical attack. Traditionally used in the production of aluminum by lowering the melting point of alumina, this compound’s incorporation into cement and concrete is relatively novel. Aluminum fluoride’s utility in the construction sector is predicated on its ability to modify the physicochemical properties of the cement paste, improving the material’s performance and durability in severe environmental settings such as industrial areas with high fluoride emissions or corrosive environments.
