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
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).
Syntheses of polycarboxylate superplasticizers: Microwave
An eco-friendly and high-efficient preparation approach to synthesizing polycarboxylate superplasticizers (PCE) co-polymers based on microwave induction was described. . Meanwhile, a series of detailed comparative studies about the effects of microwave induction and conventional thermal inductions on the conversion rate and reactivity ratio in the polymerization reaction, molecular structure
Polycarboxylate Superplasticizers | Supercizer PCE | Fritz-Pak
This unique blend of water-reducing chemicals provides substantially more benefits than previous superplasticizers. In fact, Fritz-Pak’s Supercizer PCE provides up to 40% water reduction and up to an eight-inch slump reduction in most concrete mix designs.
Technical optimization and life cycle assessment of
With the rapid development of the construction industry, it is necessary to synthesize environment-friendly functional polymers, especially when developing "green" construction industry types. Herein a novel solid-state polycarboxylate superplasticizer (PCE) with low energy-consumption was designed and synthesized.
- What is polycarboxylate superplasticizer (PCE)?
- 1. Introduction 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., 2019) by dispersing agglomerated cement particles ( Zhang et al., 2020 ).
- 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.
- 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.
- Is PCE a good superplasticizer for concrete?
- Sathyan et al. reported that concrete with PCE showed better durability performance, such as the acid resistance, sulphate resistance and chloride permeability resistance, than concrete with other types of superplasticizers (eg. lignosulphates, sulphonated melamine formaldehyde, sulphonated naphthalene formaldehyde, etc.) .
- Can microwave induction make polycarboxylate superplasticizers eco-friendly?
- An eco-friendly and high-efficient preparation approach to synthesizing polycarboxylate superplasticizers (PCE) co-polymers based on microwave induction was described.
- Do superplasticizer products impact the environment?
- However, few systematic reports have been made detailing the environmental impacts of superplasticizer products (including the synthesis, packaging, and transportation, among others) with LCA methodology. This research aims to fill this gap.
