Superplasticizer - an overview | ScienceDirect Topics
Superplasticizers are a fundamental ingredient for lowering the yield stress of concrete. This chapter provides an overview of the chemical classes of superplasticizers and their performance, with a selective review of those aspects that we consider important in understanding superplasticizers. We also demonstrate the consistency in findings
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).

pumped concrete. It contains polycarboxylate ether polymers and is specially formulated to give exceptionally high water reduction and significantly improved slump retention compared to conventional superplasticizer. MasterPolyheed 8126 is free of chloride and has been formulated to comply with Chinese Standard
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.
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 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?
- Polycarboxylate superplasticizer (PCE) is a high-range water reducer used in concrete or cement. It enhances the fluidity of concrete without compromising its strength. Composed of polycarboxylate ether polymers, PCE works by dispersing cement particles. This results in higher concrete strength and durability.
- 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.
- 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.
- What is the shelf life of polycarboxylate superplasticizer (PC-F/R/E)?
- Polycarboxylate Superplasticizer (PC-F/R/E) is available in 1100 kg / IBC tank, 230 kg / drum or flex tank. For site installations, deliveries will be made in bulk to site storage tanks. ■ Polycarboxylate Superplasticizer has a shelf life of 12 months provided it is stored under cover and out of direct sunlight.
