POLYCARBOXYLATE SUPERPLASTICIZER(PCE) - LIGNOSULFONATE
Product Description. POLYCARBOXYLATE SUPERPLASTICIZER(PCE) is a dry powdered polycarboxylate superplasticizer, with a long polyoxyethylene (PEO) chain and a terminal carboxylic group was synthesized from a modified polyether (SAE-IPEG) to increase its performance in cement , electronegative carboxylic acid group as a terminal group into the long polyoxyethylene chain of PCE, which reduced the
Polycarboxylate Superplasticizers - Concrete Construction
Some 20 years ago, a new type of superplasticizer based on polycarboxylate polymers (PCE) was commercially introduced to the North American concrete construction industry. Just as the application of naphthalene-based admixtures starting in the 1970s enabled significant improvements in the numerous engineering properties of plastic and hardened
Progresses in Synthesis of Polycarboxylate Superplasticizer
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 Superplasticizer Powder & Liquid for Concrete
Kingsun Polycarboxylate Superplasticizer (PCE) for Sale As a leading manufacturer of PCE based admixture in China, Kingsun can provide three types of polycarboxylate concrete admixtures and factory price for all the customers. They are PCE liquid for high water reduction and PCE liquid for High Slump Retention, and PCE powder.
Research progress on polycarboxylate based superplasticizers
Polycarboxylate ether/ester (PCE) superplasticizers are widely used due to their molecular structural designability, low dosage and high efficiency. However, their high sensitivity and strong interactions with clays in concrete reduce their dispersion and water-reduction capability, which can affect the performance of concrete seriously.
- What is polycarboxylate superplasticizer?
- polycarboxylate superplasticizer is a new type concrete admixture for green concrete. It can be used in high strength concrete, high performance concrete, mass concrete and high quality flow plastic concrete. (1) A kind of anionic / non-ionic liquid admixture, low-chloride, low-alkali, non-toxic, free effect on ecological environment.
- Are polycarboxylate superplasticizers good for concrete admixture?
- Polycarboxylate superplasticizers have become one of the most important superplasticizers in the concrete admixture market, that’s due to its outstanding advantages, such as high water-reducing rate, good effect, good adaptability with cement, and slump protection performance.
- What is the water reduction rate of polycarboxylate based superplasticizer?
- They are PCE liquid for high water reduction and PCE liquid for High Slump Retention, and PCE powder. Although their appearance and specifications are different, the water reduction rate of polycarboxylate based superplasticizer can reach more than 25%. The following is the detailed introduction:
- What is polycarboxylate superplasticizer (high slump retention)?
- Polycarboxylate superplasticizer (High Slump Retention) is clear transparent liquid. It is designed to enhance concrete workability and maintain a high slump for extended periods. What’s more, PCE superplasticizer also shows great performance in hot environments.
- What is Polycarboxylate ether superplasticizer?
- Polycarboxylate ether superplasticizer, also known as PCE superplasticizer, is a third-generation high-performance superplasticizer. It has the characteristics of high water-reducing rate, good slump retention performance, designable molecular structure, and environmental protection.
