Progresses in Synthesis of Polycarboxylate Superplasticizer
It was shown in Fourier transform infrared spectroscopy (FITR) that the molecular structure of modified polycarboxylate superplasticizer (MPCE) contained sulfonic acid groups, carboxylic acid groups, polyethylene oxide vinyl groups, and other groups and had comb-shaped molecular structure.
Polycarboxylate Superplasticizers - Concrete Construction
The PCE superplasticizer replaced both the PNS/lignin and Type A water-reducing products at about one-third the dosage rate. Also, note the 50% drop in AEA dosage rate with the PCE admixed concrete to obtain the same air content.
POLYCARBOXYLATE SUPERPLASTICIZER (PCE) - Sure Chemical
Polycarboxylate superplasticizer (PCE) is also called polycarboxylate ether superplasticizer, polycarboxylic ether based superplasticizers, polycarboxylate admixture, polycarboxylate type of superplasticizer. Also you can get its information by searching "PCE chemical" or "polycarboxylate ethers".

- What is a polycarboxylate ether superplasticizer?
- The polycarboxylate ether superplasticizer is an additive commonly used in concrete engineering and has a wide range of applications. The PCE based admixture can significantly reduce the amount of cement and improve the fluidity and pumpability of concrete while ensuring the strength and durability of concrete.
- 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.
- What is Polycarboxylate ether (PCE)?
- Polycarboxylate ether (PCE) is a new generation of superplasticizer, which was invented in 1981 , following the development of conventional lignosulfonate water reducing agent, naphthalene, and melamine-based superplasticizers.
- What is polycarboxylate superplasticizer (PCE)?
- As one important auxiliary, superplasticizers have attracted lots of attention in the concrete and building materials field. Specially, polycarboxylate superplasticizer (PCE) has been widely applied due to its relatively low doping amount, high water reducing rate and environmental friendliness property.
- What are the advantages of polycarboxylate based superplasticizer?
- Low dosage and high water reduction rate. The water reduction rate of polycarboxylate based superplasticizer can be as high as 45%, which can be used to prepare high-strength and high-performance concrete. Small loss when slump is light.
- Can polycarboxylate based superplasticizer improve the crack resistance of concrete?
- The polycarboxylate based superplasticizer can improve the crack resistance of concrete. After adding an appropriate amount of water reducing agent in concrete, the internal structure of the concrete can be improved and the contraction and cracking of concrete can be reduced.
