Adsorbed Conformations of PCE Superplasticizers in Cement
The conformations of polycarboxylate ether (PCE) type superplasticizer polymers adsorbed on the surface of MgO in cement pore solution are simulated by molecular dynamics (MD). Three types of PCEs
Polycarboxylate Superplasticizers | Supercizer PCE | Fritz-Pak
This product does not contain hazardous or corrosive materials and comes packaged in our signature, water-soluble bags for easy addition to the concrete at the job site. Supercizer PCE also includes a defoaming agent, to reduce the risk of the product entraining unwanted air into the concrete. More About Polycarboxylate Superplasticizers
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-1). 1. Introduction Polycarboxylate Superplasticizer (PCE) has become the most widely used admixture in the world due to its high water-reducing rate, environmental friendliness and strong molecular designability [1]. However, with the increasingly fierce competition in the market of polycarboxylate
Synthesis and Properties of a Polycarboxylate
Polycarboxylate superplasticizers (PCEs) emerged as one of the most important superplasticizers for concrete due to their superior performance. (1,2) Compared to other products like polycondensates, they fluidize cement even at low water to cement ratios, require relatively low dosages, and exhibit a long slump retention capability. (35) The
- 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 polycarboxylate superplasticizer (PCE)?
- Polycarboxylate superplasticizer (PCE), also known as polycarboxylate ether superplasticizer, is a new generation of high-performance concrete admixture.
- What is et-PC polycarboxylate superplasticizer?
- ET-PC polycarboxylate superplasticizer can greatly improve compactness, freeze-thaw resistance, carbonation resistance, elastic modulus and impermeability; reduce drying shrinkage and creep of concrete. (8) A stable performance, non-precipitation. Powder pack: woven fabric bag with plastic liner.
- What is PCE Based admixture?
- 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. Therefore, PCE superplasticizer can be widely used in these projects, such as water conservancy, eletrical power, ports, railway ,bridge, highway and buldings,etc.
- 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.
- What is the packing size for PCE powder?
- For PCE Powder, the packing is 25 kg PP woven bags. As a professional PCE superplasticizer manufacturer in China, Kingsun can provide three different types of polycarboxylate superplasticizers for you, they are PCE powder, PCE (High Water Reduction) liquid, PCE (High Slump Retention) liquid.
