  • 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.
  • Can superplasticizers be used in high-performance concrete?
  • The utilization of superplasticizers in the production of concrete offers several benefits such as improved workability, reduced water content, and increased strength. Nevertheless, the addition of superplasticizers in high-performance concrete may present challenges due to various factors.
  • What are superplasticizers used for?
  • These materials can result in as high as 40% reduction in the water content. Thus, they are perfect in making high- and ultra-high-strength concrete with a water/cement ratio as low as 0.20. Usually, these superplasticizers show excellent retention of slump and do not delay the gain of concrete strength.
  • Can polycarboxylate superplasticizer improve dispersing performance in cement paste?
  • X. Shu et al., Tailoring the solution conformation of polycarboxylate superplasticizer toward the improvement of dispersing performance in cement paste.
  • Are carboxylate based superplasticizers more effective than SNF-Based super plasticizers?
  • The authors reported that the carboxylate-based (PCE, PCS) superplasticizers are more effective than SNF-based superplasticizers. Under the same dosage, carboxylate-based superplasticizers were able to obtain mortars with considerably reduced yield stress point and low workability loss unlike the case with SNF-based superplasticizers.
  • Does the adsorption capacity of polycarboxylate superplasticizer molecules increase with backbone charge density?
  • The study shows that the adsorption capacity of polycarboxylate superplasticizer molecules increases with backbone charge density, therefore decreasing the yield stress and plastic viscosity of cement paste up to saturation dosage.
