In some places, pipes are moistened only by adding cement and water or preparing some mortar on site. This method will delay the construction progress, and the quality of the cement slurry and mortar prepared on site is unstable and can easily cause pump blockage, so it is not recommended.
If the water problem is really difficult to solve, you can directly place the lubricating pump in the pump chamber of the pump truck and stir for 5-10 minutes. </p
