Technical optimization and life cycle assessment
Polycarboxylate superplasticizer (PCE), when applied in cement-based materials such as cement paste, mortar and concrete, can significantly improve the workability, strength and durability of the material (Zheng et al., 2025) by dispersing agglomerated cement particles (Zhang et al., 2025).

Synthesis and Properties of a Polycarboxylate
Polycarboxylate superplasticizers (PCEs) are comb-shaped polymers with an anionic backbone and several nonionic pendant chains, which typically are comprised of polyethylene glycols. In this study, the synthesis of a new type of superplasticizer is presented, which does not exhibit the typical comb-shaped form of PCEs but is built up from a linear polyetheramine and a hyperbranched
Surface Modification of Nano‐SiO2 Particles with
This study presents an innovative eco-friendly method, which improves the distribution of NS particles through their surface modification using polycarboxylate ether-based (PCE) superplasticizer containing silane coupling agent under microwave irradiation. The above method ensures the formation of a core-shell-shell… View via Publisher
Polycarboxylate Superplasticizer (PCE) For Concrete
Polycarboxylate superplasticizer (PCE), also known as polycarboxylate ether superplasticizer, is a new generation of high-performance concrete admixture. It is a water reducing agent with excellent performance that integrates water reduction, slump protection, reinforcement, shrinkage and environmental protection.
- What is a polycarboxylate superplasticizer?
- Polycarboxylate superplasticizers (PCEs) are comb-shaped polymers with an anionic backbone and several nonionic pendant chains, which typically are comprised of polyethylene glycols. In this study,...
- Is solid-state polycarboxylate superplasticizer better than liquid-state PCE?
- Herein a novel solid-state polycarboxylate superplasticizer (PCE) with low energy-consumption was designed and synthesized. In industrial application, solid-state PCE has exhibited better cement paste fluidity and concrete slump compared to liquid-state PCE.
- Can amide-structural polycarboxylate superplasticizer be used in concrete?
- Furthermore, the application performances of amide-structural polycarboxylate superplasticizer in concrete shows a great similarity to that of conventional PCEs, and also has better air-entraining ability, bubble retention and concrete frost-resistance than those of conventional PCEs .
- What is a modified polycarboxylate (MPC) superplasticizer?
- A modified polycarboxylate (MPC) superplasticizer was synthesized by the copolymerization of acrylic acid, methallyl sulfonic acid, allyl poly (ethylene glycol)s, and β-cyclodextrin (β-CD) grafted…
- How are acrylate-containing polycarboxylate superplasticizers synthesized?
- Acrylate-containing polycarboxylate superplasticizers were synthesized by copolymerizing acrylic acid, α-methallyl-ω-methoxy poly (ethylene glycol) ether, and acrylic esters [hydroxyethyl acrylate…
- Does a PCE superplasticizer deteriorate GWP based on low carbon binders?
- This calculation suggests that even for a worst-case scenario where a PCE dosage of 2.5 % by weight of concrete is applied, the PCE superplasticizer does not deteriorate the favorable GWP of concretes based on low carbon binders.
