  • What is a comblike polycarboxylate superplasticizer?
  • Comblike polycarboxylate superplasticizers (PCs) have been widely used as construction and building materials by means of high fluidity and fine dispersibility via electrostatic repulsion and steric hindrance.
  • Are polycarboxylate based superplasticizers a new era in concrete technology?
  • In particular, the emergence of polycarboxylatebased superplasticizers marks a new era in concrete technology.
  • Who invented polycarboxylate superplasticizers?
  • To read the full-text of this research, you can request a copy directly from the authors. 2021 marks the 40th year since polycarboxylate superplasticizers (PCEs) have been invented by Nippon Shokubai company in Japan. This invention clearly represents a major breakthrough and milestone in modern concrete technology.
  • What are polycarboxylic acid dispersants?
  • The research on polycarboxylic acid dispersants began in the 1980s and was invented by Japanese scholars. They are environmentally friendly and can make concrete have good water reduction, workability and flow retention, and are widely used in the concrete industry .
  • What are PCE superplasticizers made of?
  • The PCE superplasticizers are comb-shaped polymers, 26 which contain polypropylene glycol groups and carboxylic acid anhydride monomers consisting of acrylic acid, maleic acid, and its anhydride. ... ...
  • What is a comb shaped copolymer (PCE)?
  • PCEs are comb-shaped copolymers 26,27 and constitute the thirdgeneration of high range water reducing admixture known as superplasticizer. Lei et al. 28 presented a state of the art review on the use of PCEs in the past 40 years.
