Progress in the polycarboxylate superplasticizer and their structure-activity relationship ¨C A review - ScienceDirect

Specially, polycarboxylate superplasticizer (PCE) has been widely applied due to its relatively low doping amount, high water reducing rate and environmental friendliness property. In this review, the properties of PCE were systematically investigated based on their different molecular architecture, anchoring groups, various main/side chains and diverse topological structures.

Polycarboxylate ether superplasticizer with gradient structure: excellent dispersion capability and sulfate resistance | Colloid and

In this paper, gradient and block polycarboxylate ether superplasticizers (PCEs) composed of allyl alcohol polyoxyethylene ether macromonomer and acrylic acid were synthesized via aqueous reversible addition-fragmentation chain transfer (RAFT) polymerization. The molecular structure of PCEs was characterized by 1H nuclear magnetic resonance (NMR), Fourier transform infrared (FT-IR

Synthesis of Modified Polycarboxylate and Its Application in Ultra-High Performance Concrete - Frontiers

Modified polyurethane prepolymer was prepared using the segmental synthesis method. Then, pectiniform polycarboxylate was synthesized at normal temperature in the complex initiation system of H2O2, APS, sodium bisulfite, Vc, and Rongalit according to the free radical polymerization reaction mechanism, using TPEG, AA, and PEG as raw materials and TGA as the chain transfer agent. Compared with

Low-cost synthesis of high-performance polycarboxylic ether by Co2+-, Ni2+- and Zn2+-catalyzed H2O2-NaHSO3 initiation system - Springer

As a new type of high-performance water-reducing agent, polycarboxylate ether (PCE) has excellent properties such as small dosage and high water reduction rate. However, it is still necessary to develop a synthetic process to improve the performance of PCE at a low cost. In this paper, Co2+-, Ni2+- or Zn2+-catalyzed H2O2-NaHSO3 redox initiation system is designed as a new cost-effective

Synthesis of Comb-Polyurethane-Modified Polycarboxylate at Indoor Temperature and Its Interaction With Portland Cement - Frontiers

According to the principle of radical polymerization reaction, different polycarboxylates with comb structures were synthesized. With the other two commercial polycarboxylates (C-PCE-1 and C-PCE-2), the effects of all the polycarboxylates on adsorption, hydration, zeta potential, liquid surface tension, and flowability in Portland cement were determined. Compared to O-PCE and C-PCEs, the
