Research progress on polycarboxylate based superplasticizers
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.
Progresses in Synthesis of Polycarboxylate Superplasticizer
The prerequisite to synthesize PCE was to prepare new macromonomers with controlled molecular mass, adjustable hydrophilic-lipophilic groups, long-chain alkyl groups, and large terminal hydroxyl groups as well. 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
Synthesis and Properties of a Polycarboxylate
Polycarboxylate superplasticizers (PCEs) emerged as one of the most important superplasticizers for concrete due to their superior performance. (1,2) Compared to other products like polycondensates, they fluidize cement even at low water to cement ratios, require relatively low dosages, and exhibit a long slump retention capability. (35) The

South America (Brazil, Argentina, Columbia etc.) Middle East and Africa (Saudi Arabia, UAE, Egypt, Nigeria and South Africa) ... 8 Global Polycarboxylate Superplasticizers Market Forecast (2025
- How are polycarboxylate superplasticizers synthesized?
- In this work, a series of polycarboxylate superplasticizers (PCEs) were synthesized via copolymerization using a novel macromonomer, ethylene–glycol monovinyl polyethylene glycol (EPEG). The molecular structures were modified by varying the side chain length, carboxylate density and integrating sulfonic group.
- What are cross-linked polycarboxylate superplasticizers?
- In this context, a series of cross-linked polycarboxylate superplasticizers were synthesized using acrylic acid, methylallyl polyoxyethylene ether and four different cross-linkers containing ester groups, respectively.
- Are cross-linked sustained-release polycarboxylate superplasticizers a good alternative to comb-type poly carboxy?
- Cement system properties (adsorption, hydration, compressive strength etc.) were determined. Cross-linked sustained-release polycarboxylate superplasticizers (SPs) are superior alternative to the comb-type polycarboxylate SPs due to they offer both a high fluidity and a good retention effect for concrete slurry.
- 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.
- Can cross-linked polycarboxylates be synthesized?
- The above results along with FT-IR data described earlier both indicated the targeted cross-linked polycarboxylate SPs was successfully synthesized. Fig. 3. 13 C-NMR spectra of SPT-0. 3.2. Dispersion property of the cross-linked SPs 3.2.1. Fluidity of the cross-linked SPs in cement paste and water reduction ratio in mortar
- What is Polycarboxylate ether/ester (PCE) superplasticizer?
- 1. Introduction Polycarboxylate ether/ester (PCE) superplasticizer is a new generation of superplasticizer following the development of poly (naphthalene sulfonate) (PNS), poly (melamine sulfonate) (PMS) and acetone formaldehyde sulfite (AFS) superplasticizers.
