Effect of Functional Polycarboxylic Acid Superplasticizers on
Modern engineering practices require that polycarboxylic acid high-performance superplasticizers have good adaptability to various environments and materials, which indicates the importance of
Polycarboxylate Superplasticizer (PCE) For Concrete - Kingsun Chemicals
It is a new generation of polycarboxylate ether polymer, which can be used as a superplasticizer for cement-based materials. Polycarboxylate powder is also an excellent dispersing plasticizer for mineral materials such as gypsum and ceramics. 2. High Water Reduction. PCE water reducer is a ready-to-use liquid superplasticizer.
Concrete Water Reducer - Superplasticizers
7. Since the dosage of polycarboxylic acid superplasticizer is very small, the water reduction rate is high. The use of polycarboxylic acid superplasticizers to prepare various types of high-performance concretes above C45 can greatly reduce project costs and has significant technical and economic benefits; it is used to prepare concrete below C45, although the cost of polycarboxylic acid

- What is polycarboxylate superplasticizer?
- Polycarboxylate superplasticizers (PCEs) are indispensable functional ingredients in modern construction, and their usage is extensive. Herein, a polyether macromonomer (VPEG) with high reactivity was used to prepare VAPCEs with different interfacial adsorption properties (acid–ether ratio) at low temperatures and reacted in 30 min.
- 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.
- Does polycarboxylic superplasticizer affect dispersion and water retention?
- The molecular-scale structural changes in polycarboxylic superplasticizer (PCE) can influence dispersion and water retention. Polycarboxylate superplasticizer, synthesized using different methods, may alter dispersion and water-reducing effects.
- Do polycarboxylic superplasticizers increase hydration products?
- The hydration products of C 3 A and C 4 AF in the PC increased with an increase in the dosage of polycarboxylic superplasticizers, and the ζ potential became positive as they become positively charged [76, 77].
- 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.
- Why are linear polycarboxylic copolymers better than comb-PCE?
- Compared with comb-PCE, linear polycarboxylic copolymers with low molar masses are easier to be adsorbed by clays owing to their high degree of diffusion freedom, and are also good dispersants for decrease in viscosity .
