Research progress on polycarboxylate based superplasticizers
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.
Optimizing Polycarboxylate Based Superplasticizer Dosage with
In this study, the optimum dosages of several brands of PCE superplasticizer in making mortar were investigated. Two different cement types were used. The effect of SP on flowability, setting time, and resulting compressive strength were evaluated. The results show that with the increase of SP dosage in mortar mixture, the flowability increased.

- Who makes Polycarboxylate ether?
- Connect Today! TriStar Technical Co. owns and operates the first commercial PolyCarboxylate Ether manufacturing facility in Saudi Arabia. PCEs are modern concrete superplasticizers, used to produce high-performance concrete.
- What is a polycarboxylate ether (PCE) superplasticizer?
- Polycarboxylate ether (PCE) superplasticizers have a variety of uses such as improving concrete liquidity and pumping, reducing water-ash ratio, improving crack resistance, improving early intensity and saving cement dosage.
- 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.
- How to store PCE polycarboxylate superplasticizer?
- The PCE polycarboxylate superplasticizer should be stored in a cool, dry and well-ventilated place, avoiding direct sunlight and rain. At the same time, it should be kept away from fire and heat sources to prevent fire or explosion accidents. Water seepage problem.
- How can Polycarboxylate ether reduce water and gray ratio?
- Reduce concrete water and gray ratio. Polycarboxylate ether superplasticizer can form a decentralized adsorption film in the concrete, reducing the contact between water and cement particles, thereby reducing the concrete water and gray ratio. By reducing the water and gray ratio, the strength and durability of the concrete can be improved.
- 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.
