Which is better, Shangfeng Cement or Yufeng Cement?

Shangfeng cement has better cement, faster solidification and stronger structure.

Cement: powder hydraulic inorganic cementing material. Mud can be hardened in air or water after being mixed with water, and can firmly bond sand, stone and other materials together. The mixture of early lime and pozzolan is very similar to modern lime-pozzolan cement. After hardening, the concrete made of crushed stone not only has high strength, but also can resist the erosion of fresh water or salt water. For a long time, as an important cementing material, it has been widely used in civil engineering, water conservancy, national defense and other projects.
