  • What is polycarboxylate superplasticizer?
  • Polycarboxylate superplasticizers (PCEs) are indispensable functional ingredients in modern construction, and their usage is extensive. Herein, a polyether macromonomer (VPEG) with high reactivity was used to prepare VAPCEs with different interfacial adsorption properties (acid–ether ratio) at low temperatures and reacted in 30 min.
  • What are structural changes in polycarboxylate superplasticizer (PCE)?
  • Structural modifications in the molecular scale of polycarboxylate superplasticizer (PCE) would lead to changes in properties of dispersion and water retention as well as enhancement in the compatibility of Portland cement and so on.
  • Does polycarboxylate super-plasticizer improve microstructure of concrete?

  • Do Polycarboxylate ether/ester superplasticizers affect concrete performance?
  • Polycarboxylate ether/ester (PCE) superplasticizers are widely used due to their molecular structural designability, low dosage and high efficiency. However, their high sensitivity and strong interactions with clays in concrete reduce their dispersion and water-reduction capability, which can affect the performance of concrete seriously.
  • How are gradient and block Polycarboxylate ether superplasticizers synthesized?
  • In this paper, gradient and block polycarboxylate ether superplasticizers (PCEs) composed of allyl alcohol polyoxyethyl-ene ether macromonomer and acrylic acid were synthesized via aqueous reversible addition-fragmentation chain transfer (RAFT) polymerization.
  • How are amide-structural polycarboxylate superplasticizers produced?
  • In another study by Liu et al. , amide-structural polycarboxylate superplasticizers (amide-PCEs) were produced by amidation reaction between polyacrylic acid (PAA) and amino-terminated methoxy polyethylene glycol (amino-PEG) at 130–150°C.
