Progresses in Synthesis of Polycarboxylate Superplasticizer - Hindawi
The prerequisite to synthesize PCE was to prepare new macromonomers with controlled molecular mass, adjustable hydrophilic-lipophilic groups, long-chain alkyl groups, and large terminal hydroxyl groups as well. Structural modifications in the molecular scale of polycarboxylate superplasticizer (PCE) would lead to changes in properties of dispersion and water retention as well as enhancement in
Polycarboxylate ether superplasticizer with gradient structure
Polycarboxylate ether (PCE) is a new generation of superplasticizer, which was invented in 1981 [ 6 ], following the development of conventional lignosulfonate water reducing agent, naphthalene, and melamine-based superplasticizers.

Polycarboxylate superplasticizer is a kind of surfactant containing carboxyl grafted copolymer in molecules, and its unique molecular structure makes it have many unique advantages, such as low dosage, high water reduction rate, significant early strength growth, satisfactory keeping slump, no
- 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 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.
- What is polycarboxylate superplasticizer (PCE)?
- Polycarboxylate superplasticizer (PCE), also known as polycarboxylate ether superplasticizer, is a new generation of high-performance concrete admixture.
- What is Kingsun Polycarboxylate ether superplasticizer?
- Kingsun Polycarboxylate ethers are superplasticizers that have a great strength effect on concrete. They can improve the impermeability, frost resistance, and durability of concrete. Kingsun Polycarboxylate ethers can make concrete have good liquidity and small slump loss at high temperatures.
- What is Polycarboxylate ether (PCE)?
- hardened material and produces a more durable concrete with better mechanical performances . Polycarboxylate ether (PCE) is a new generation of superplasticizer, which was invented in 1981 , following the development of con-ventional lignosulfonate water reducing agent, naphthalene, and melamine-based superplasticizers.
- What is Polycarboxylate ether powder?
- Polycarboxylate ether powder is a high-performance and environmentally friendly product. It has the characteristics of good dispersibility, high water reduction rate, and good adaptability with various cements. Other features include being green and pollution-free. The packing options for PCE liquid are 230kg PE drum, 1100kg IBC tank, or flexitank.
