[0002] Sand and gravel aggregate is a general term for materials such as sand, gravel (pebble), crushed stone, block stone, and dressed stone in water conservancy projects. Sand and gravel aggregate is the main building material for concrete and masonry structures in water conservancy projects. Aggregate with a particle size greater than 5m is called coarse aggregate, that is, the gravel we often mention, and aggregate with a particle size less than 5m is called fine aggregate, also known as sand. Sand and gravel are the main building materials for concrete and masonry structures in water conservancy projects. Sand and gravel aggregate is the main material for producing concrete in construction, and the building materials produced by sand and gravel aggregate with different particle sizes have different properties and uses. Therefore, screening sand and gravel is an important process in the concrete production process.
