[0002] Ordinary concrete refers to artificial stone made with cement as the main binder, water, sand, gravel, and, if necessary, chemical admixtures and mineral admixtures, proportioned appropriately, uniformly stirred, densely formed, and cured and hardened. Concrete is mainly divided into two stages and states: the plastic state before setting and hardening, i.e., fresh concrete or concrete mixture; and the hard state after hardening, i.e., hardened concrete or concrete.

[0003] In most cases, the settlement of powder is due to the degassing of powder particles. The air trapped between the particles can escape over time through compression and separation effects.

Thermal changes or exposure to moisture and humidity are also factors contributing to some caking of the powder materials. When the powder materials cake, when using a conveying pipe to transport the powder materials, the pressure on the screw conveyor rod is relatively large, which easily causes slow material transportation.
