Water Reducing Agent for Concrete （3)——Mechanism of Dispersion-fluidization Effect
摘要
Abstract
The mechanism of dispersion-fluidization effect of ACS on cement particles was discussed. The measurements of ζ-potential indicated that electrostatic repulsion is one of the physical factors. The other affecting factor is stereo hindrance,which was found from the influences of n on fluidity of cement grout. Surface tension is another one.chemical affecting factors include the retarding effect of ACS on cement hydration as well as the slow releasing of —COO- of copolymer molecules with time under alkaline condition .关键词
