Aggregates, both fine and coarse, constitute about 60 -80% of the concrete formula. Mixed together with cement and water, the aggregate element helps make concrete more compact, provide strength, durability and workability. These properties make concrete one of the most widely used materials across the world. It is used to construct skyscrapers ...
