| Abstract: | Concrete pumping is to use pump compression force to transport concrete along the pipeline to casting point. The concrete of to be pumped to 173m height is the first class concrete, different from other ordinary concrete. It hasspecial requirements for raw materials, more requirements for mix ratio design and construction than ordinary concrete. |
