Effect of Ether-Typed Polycarboxylate Superplasticizer on the Adsorption, Rheology and Concrete Properties

Abstract:

This article disclosed the influence of acid-ether ratio, n₍_SH)/n_(IPEG), and n_(APS)/n_(IPEG) on adsorption and fluidity performance. The optimum synthetic parameters of acid-ether ratio, n₍_SH)/n_(IPEG) and n_(APS)/n_(IPEG) were 0.5, 0.35 and 0.05, respectively. The rheology fitting equation was τ= 719.55γ+ 1834.54. And the correlation coefficient was 0.9843. The cement paste conformed to the law of pseudoplastic fluid. The preferred PCE-11 had excellent performance in freshly mixed and hardened concrete.
