Concrete pumping concrete pumping agent is used to improve the performance of the additives, mainly used in production of commodity concrete mixing station and on-site mixing of concrete pumping concrete pumping, concrete strength requirements C40, C50, C60, pumping height from 100 meters, 200 meters to 350 meters; large volume of concrete from the thousands of cubic meters to tens of thousands of cubic meters, thus, concrete pumping agent with the following conditions: (1) Concrete mixing station can meet the process requirements. (2) with air-entraining, retarding, water reducing, enhanced lubricating ability, it can greatly improve the workability of fresh concrete, concrete without segregation bleeding, easy pumping, slump loss is small, hardened concrete the key physics properties meet design requirements. (3) the use of the product after mixing the concrete to harden to have better surface quality. Concrete pumping agent is mainly composed of water-reducing components, bleed air component, adjusting coagulation components, enhanced components, slump loss restrain the agent. Results of this study reach the leading level in China, into the international advanced level products play a major construction project in Shanghai effectiveness: WL-1-type pumping agent for the Hai Lun Hotel 8600 cubic meters based on the basis of the Yangpu Bridge, 15,000 cubic meters, with WL-1-type mixing of concrete for the large volume of goods, extra-thick concrete foundation created conditions for high-speed construction. Nampo series pumping agent for the world's third cable-stayed bridge - Nanpu Bridge Tower concrete (C40, a pump to 154 meters) and the first century, cable-stayed bridge - the Yangpu Bridge Tower concrete (C50, a pump to 208 m), JRC-2D series for the Oriental Pearl - Shanghai TV Tower C60 pumping post-tensioned high strength concrete (a pump to 180 meters), C50 concrete (a pump to 225 meters), C40 high range concrete pump (a pump to 350 meters), the physical properties of concrete meet the design requirements, a better quality of the concrete surface for high strength concrete pumping process to resolve key technology. 2001, the latest successful development of polycarboxylate superplasticizer for domestic initiative, achieved only in Japan, the United States and a few other countries can produce a new generation of superplasticizer performance. Has been in Shanghai "maglev" rail girder applications.
