Sand Aggregate

Sand and gravel aggregate is a general term for sand, egg (gravel) stone, gravel, block stone, stone and other materials in water conservancy projects. Sand and gravel aggregates are the main building materials for structures such as concrete and masonry. Aggregates with a particle size greater than 5mm are called coarse aggregates, which we often call stones. Aggregates with a particle size less than 5mm are called fine aggregates, also known as sand. The main raw materials are limestone granite basalt river pebbles.

Limestone is mainly composed of calcium carbonate (CaCO3), Mohs hardness 3. After limestone is mined from limestone, it is crushed to form limestone particles, I .e. stone and sand, or further ground to form limestone powder, which is widely used in building materials, highways, metallurgy, chemical industry and other industries.



Granite has uniform structure, hard texture, beautiful color and durability. It is a high-quality building stone and is known as "rock. Granite is not easy to weather, and its appearance and color can be maintained for more than 100 years. It belongs to intrusive rocks in acidic (SiO2>66%) magmatic rocks.



Basalt, the main composition of oceanic crust, is a basic volcanic rock. It is the most important component of the earth's oceanic crust and the moon and sea, and it is also an important component of the earth's continental crust and the moon and land. It is harder and wear-resistant than alloy steel, and more corrosion-resistant than lead and rubber. Basalt is also used as a "lubricant" in an advanced steel casting process, which can extend the life of the cast film. At the same time, basalt can also be pumped into glass wire, which is stronger than ordinary glass wire cloth in alkali resistance and good in high temperature resistance. 


River Pebbles

River Pebbles/pebbles are hard solids shaped like goose eggs formed after thousands of years of landscape impact and water transportation. Its main component is silica. The artificial sand and gravel produced by them meet the requirements of various places for artificial sand and gravel. 


Machine-Made Sand

Machine-Made Sand refers to sand processed by sand making machine and other auxiliary equipment. The finished product is more regular and can be processed into sand of different rules and sizes according to different technological requirements, which can better meet daily needs.
