Synthesis and Performance of Polycarboxylic Acid
A new type of polycarboxylic acid superplasticizer (G18-PCEs) containing crosslinked linkage was synthesized by the method of the first esterification and then polymerization. Its monomer and polymer structure were confirmed by 1H nuclear magnetic resonance (NMR) spectroscopy and High-performance liquid chromatography.
Synthesis of polycarboxylic ether superplasticizers based on
Generally, polycarboxylic ether superplasticizer (PCEs) have excellent properties of high water reduction and high slump retention capacity, and they are widely used in engineering [1], [2], [3], [4]. In the synthesis of PCEs, the types of macromonomers are extremely important.

Low-cost synthesis of high-performance polycarboxylic ether
As a new type of high-performance water-reducing agent, polycarboxylate ether (PCE) has excellent properties such as small dosage and high water reduction rate. However, it is still necessary to develop a synthetic process to improve the performance of PCE at a low cost.
- What is polycarboxylate superplasticizer?
- polycarboxylate superplasticizer is a high-performance water reducing agent. It is a cement dispersant used in cement concrete applications. Polycarboxylate concrete superplasticizer is widely used in roads, bridges, dams, tunnels, high-rise buildings and other projects.
- 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.
- 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.
- What is PCE superplasticizer?
- PCE superplasticizer is a high-performance water reducing agent that integrates many functions such as high water reduction, high collapse retention, reinforcement, shrinkage, and environmental protection. It is also an ideal admixture for preparing high-strength and high-performance concrete.
- 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.
- Does polycarboxylate water reducer reduce cement dosage?
- Save cement dosage. Polycarboxylate water reducer can significantly reduce the amount of cement dosage of concrete and save costs. By adding an appropriate amount of water reducing agent, you can reduce the amount of cement without reducing the strength of the concrete to achieve the purpose of saving costs.
