Polycarboxylate Superplasticizer (PCE) For Concrete
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. It is light yellow in appearance. Besides, it can be completely water easily.
Development of lignin-based polycarboxylates as a plasticizer
Plasticizers, such as lignosulfonate (LS) or polycarboxylate ether (PCE), have been used to reduce the amount of added water in cement paste, which is advantageous because water reduces the strength of hardened cement (Plank et al. 2010; Huang et al. 2018).
INNOSPEC Special Defoamer - INNOSPEC
Tunneling Special Defoamer for Concrete Admixture Formulations DEHSCOFIX WL660 Defoamers are crucial components in the formulation of polycarboxylate ether (PCE) superplasticizers. One side-effect of using a PCE superplasticizer is that they pull an excess of air into the concrete slurry.
Poly(carboxylate ether)-based superplasticizer achieves
Latest generations, poly (carboxylate ether)-based superplasticizers, (PCEs), have acrylate groups in the backbone and also contain side chains (i.e., poly (ethylene oxide)) that protrude from...
Superplasticizer
Super plasticizers are synthetic polymers. Compounds used as superplasticizers include sulfonated naphthalene formaldehyde condensate, sulfonated melamine formaldehyde condensate, acetone formaldehyde condensate and polycarboxylate ethers.
- 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 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.
- 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 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.
- 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.
