Crushed stone powder is used to make concrete blocks and precast concrete. This is used to fill in the forms to create structural elements in buildings such as beams, pillars, slabs and foundations. Some advantages of using slate gravel in concrete: greater durability, due to the high resistance of slate; slate absorbs less water, making it easier to handle the mixture and less cement can be used, which ends up optimizing costs.
The industrial waste from slate is transformed into gravel, which is used for floor concreting, land and road preparation, manufacturing of precast elements and other applications.
