Concrete pumping agent is used to improve the pumping performance of concrete admixture, mainly used in commercial concrete mixing plant production of pumping concrete and on-site mixing pumping concrete, concrete strength grade requirements C40, C50, C60, the pumping height from 100 meters, 200 meters to 350 meters; mass concrete from thousands of cubic meters to tens of thousands of cubic meters, thus, concrete pumping agent has the following conditions:
(1) Can meet the concrete mixing plant production process requirements.
(2) The comprehensive performance of air-entraining, retarding, water-reducing, enhancing and lubricating can greatly improve the workability of fresh concrete, the concrete does not separate and release the bleeding water, the pumpability is good, the loss of slump is small, Physical properties meet the design requirements.
(3) The concrete mixed with this product should have better surface quality after hardened.
The main components of concrete pumping agent for water reducing components, air entraining components, adjusting components, reinforcing components, slump loss inhibitor. The research results reached a leading level in the country, to enter the international advanced level, a series of major projects in Shanghai to play a major role: WL-1-type pumping agent for the Hailun Hotel 8600 cubic meters of foundation Yangpu Bridge 15,000 cubic meters, using WL-1-type commercial concrete mixing for large-size, ultra-thick concrete foundation to create the conditions for high-speed construction. Nanpu series of pumping agent for the world's third cable-stayed bridge - Nanpu Bridge main tower concrete (C40, a pump to 154 meters) and the first cable-stayed bridge - Yangpu Bridge Piston Concrete (C50, a pump to 208 JRC-2D series for the Oriental Pearl Tower - Shanghai TV Tower C60 post-tensioned high-strength pumping concrete (a pump to 180 meters), C50 concrete (a pump to 225 meters), C40 ultra-high pump concrete To 350 meters), the physical properties of concrete meet the design requirements, with better concrete surface quality, high strength and high pumping concrete to solve the technical key.
In 2001, the newly developed polycarboxylate superplasticizer was the first in China, reaching the performance of a new generation of superplasticizer which can be produced by only a few countries such as Japan and the United States. Has been in Shanghai "maglev" track beam production applications.
