Pump concrete

The slump of the concrete mixture is not less than 100mm and the concrete is conveyed by the concrete pump through the pipe.
Efficient Air Cooling Vacuum Pump
For its good fluidity, aggregate size is generally not larger than the diameter of the 1/4, to prevent the concrete pumping pipe blockage segregation and pumping agent, as well as the concrete mixture in the pump pressure to pass the admixture, water reducing agent, plasticizer, air entraining agent and thickener are available for pumping agent. The amount of mixing materials (such as fly ash, etc.) can be avoided in construction of concrete mixture segregation, secrete water and blockage of pipelines.

In the raw material of pumping concrete, the coarse aggregate should be preferred (Pebble).
