The selected stone particle size should not be less than 300mm. The largest stone blocks should be selected according to the transportation and storage capacity of the stone pile. When there is mud on the surface of the stone, it will affect the bonding between the aggregate and the concrete and reduce the integrity of the concrete. If there is a lot of mud and stone powder in the stone pile, after transportation and storage, such debris will accumulate at the bottom of the warehouse, which will cause the new and old concrete to be unable to combine effectively, resulting in engineering quality problems such as seepage and leakage, affecting the anti-permeability and durability of the concrete. Therefore, the mud content of the stone should be strictly controlled.

[0003] In order to ensure that the soil in the rock pile and the stone powder attached to the surface are effectively cleaned, the rock pile needs to be cleaned. There are two main ways to clean the rock pile: one is to use a high-pressure water gun to wash the rock pile in the material yard; the other is to wash the rock pile directly in the dump truck.
