Quality Gravel

Greatech’s quality gravel has been upgraded from the traditional two-level ratio to the three-level ratio, including: 5-10mm, 10-16mm, 16-25mm. The gradation is reasonable, the content of needle flakes is strictly controlled, the gravel shape is good, and it can save save cementitious material and can meet the requirements of high-strength concrete.

Quality Machine-made Sand

Strictly control the content of stone powder, MBV (methylene blue value, indicating the size of the mud content in the machine-made sand) is less than 1.0, the fineness modulus is stable, the particle morphology is round, the gradation is good, the porosity is low, which can significantly save cementitious material to improve the compactness and durability of concrete.

Quality Stone Powder

It has a wide range of uses, mainly in the fields of construction and building materials, feed processing, coal power desulfurization and chemical industries.
