[0002] Sand and gravel aggregates are indispensable materials in construction projects and are mainly used in the preparation of concrete and mortar. They include two basic components: sand and crushed stone. Sand usually comes from riverbeds, beaches or weathering of rocks. It has small particle size, regular shape, good fluidity and filling properties. Gravel is obtained by crushing and screening rocks. It has a larger particle size, high strength and bearing capacity, and is mainly used as the aggregate part of concrete.

[0003] The quality of sand and gravel aggregate directly affects the strength, durability and construction performance of concrete. High-quality sand and gravel aggregate should have good particle grading, low mud content and reasonable particle size distribution to ensure the uniformity and stability of concrete.
