Technical optimization and life cycle assessment of environment
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).

A concept for a polycarboxylate superplasticizer possessing enhanced
The MPASPs could inhibit the early cement hydration while had little effect on later cement hydration. Based on the above results, the dispersion model of MPASPs in cement–water system was also discussed. This study offered a novel environmentally friendly superplasticizer based on a biodegradable green polymer and simple synthesis method.

- What is a polycarboxylate superplasticizer (PCE)?
- Polycarboxylate superplasticizers (PCEs) prepared by traditional free radical initiation methods need to use chemicals as initiators, which are environmentally unfriendly. In contrast, photoinitiat...
- 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 .
- 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.
- 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.) .
- Is poly (aspartic acid) biodegradable?
- Although some environmentally friendly materials such as chitosan , lignin and cyclodextrin have been investigated to prepare superplasticizers, the need for biodegradable water soluble poly (carboxylic acid) is pressing. Poly (aspartic acid) (PASP) is a very promising biomaterial owing to its protein-like chain structure .
