Aggregate

Aggregate usually refers to the granular material used in concrete, which is one of the main components of concrete. Aggregates can be different types of granular materials such as crushed stone, crushed minerals, sand, etc., which are used to form a skeleton in the cement paste and enhance the strength and durability of concrete. In the field of construction and engineering, the selection and quality of aggregates have a significant impact on the performance of the final concrete product.

Common sizes of aggregates can vary depending on their use and the strength class of the concrete, generally speaking, common aggregate sizes include:

1. Coarse Aggregate (Coarse Aggregate): generally greater than 4.75 mm (0.187 inches) in diameter and commonly used in concrete to provide strength and support. Common sizes include: 20mm、16mm、12.5mm.

2. Intermediate Aggregate: generally between 4.75 mm (0.187 in.) and 9.5 mm (0.375 in.) in diameter, typically used in certain specialized concrete elements.

3. Fine Aggregate (Fine Aggregate): generally less than 4.75 mm (0.187 inches) in diameter, mainly used in filling and mortar, can fill the voids between the aggregates, improve the uniformity and durability of concrete.

These sizes can be adjusted and selected according to specific project needs and design requirements.

According to the aggregate size, you can choose our jaw crusher, impact crusher, cone crusher, sand making machine to meet your diverse needs.
