How is the mortar in concrete pumping concrete coexisting and distinguishing in a pump?
Concrete mixing truck, the first charge, should be more two bags of cement.
When the pump starts to press the concrete, the speed should be slow, when the concrete is sent to the end of the pipe, the speed can be gradually accelerated, and transferred to the normal degree of pumping.
The body should maintain a slow rotation, before discharge, the simplified speed should be accelerated to 20 ~ 30s before discharge.
Before pumping concrete, first remove the water in the hopper from the pipe to wet and clean the pipe, then press the pure water slurry or
