The finished products are of cube shape, with low content of needle-like and sheet-like products. Strong compressive capacity, meeting the need of high standard construction, such as water conservancy, bridges, superhighway and high-rise buildings and other areas.
Standard industrial production, ensuring the quality of each batch.
Polygon-like particle shape and large specific surface area. Powder content accounted for 3 to 15%. Good activity and combination.
Firm meshing between sand granules, high concrete strength and good frost resistance.
Additives are very expensive, so it can save costs.
Wide application scope, especially for high performance concrete. Can be applied to the high-rise buildings, hydropower dam, highway, railway, bridges, etc, where the natural sand are not allowed.
