Coarse aggregates include pebbles, crushed stones, waste residues, etc., and fine aggregates are mainly medium-fine sand. When mixing the concrete, the cement is mixed with water into a thin paste. If no aggregate is added, it will not be able to be shaped and will be unusable. Therefore, aggregate is a very important raw material in construction.
