Paper Title:
Less Loss of Fluidity of Polycarboxylic Acid Type Water Reducer
  Abstract

Cement paste and concrete with different molecular weight of side-chain of polycarboxylic acid type water reducer (PC) and retarder has been researched. In this way, the method of adjusting the molecular weight of side-chain and complexing retarder to hold fluidity has been discussed. The results show that with increase molecular weight of side-chain, the dispersibility and holding dispersibility increases. With retarder and PC, the dispersibility and holding dispersibility of PC with big more molecular weight of side-chain increases and the loss of fluidity at 1h prominence reduces. But it relates to breed of cement. Especially at low ratio of water and cement, when molecular weight of side-chain is more than 2000, complexing PC and retarder can improve the fluidity and holding fluidity.
