KEM SUPLAST SCC 30 is a polycarboxylic either based concrete super plasticizer, disperses the concrete medium at a substantial lower dosage than conventional concrete superplasticizers and improves consistency as well as strength. Application Areas: Self consolidated concrete. High performance concrete. Underwater concrete. Ready mix concrete.
Polycarboxylate Superplasticizer (PCE) For Concrete
It is a new generation of polycarboxylate ether polymer, which can be used as a superplasticizer for cement-based materials. Polycarboxylate powder is also an excellent dispersing plasticizer for mineral materials such as gypsum and ceramics. 2. High Water Reduction. PCE water reducer is a ready-to-use liquid superplasticizer.

a) Performance polymers for super-plasticizers 9. The performance of super-plasticizers, a type of concrete admixture, depends on the performance polymer used as input in the formulation. Performance polymers for super-plasticizers, namely polycarboxylate ether polymers (PCE), naphthalene sulfonates
- 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.
- 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 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 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.
- 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.
