What type of aggregates are recommended for the production of high strength concrete? What is an Aggregate in Construction? An aggregate is a broad category of coarse to medium-grained material used in construction, including sand, gravel, crushed stone, slag, and recycled concrete . Types of aggregates There are 2 types of aggregates. 1 Fine aggregates 2 coarse aggregates For high-strength concrete, angular crushed stone is recommended due to its rough texture, which provides superior mechanical interlocking and a stronger bond with the cement matrix. Key recommendations for high-strength concrete aggregates: Aggregate Type/Material: Crushed stone or gravel (e.g., granite) is ideal because of its durability and strength. Shape: Angular, crushed aggregates are best for high strength. They create a better bond than rounded gravel, which is poor in interlock. Size: Smaller maximum aggregate sizes (e.g., 10 mm to 12.5 mm) are preferred as they enhance bond strength ...
