Amphoteric polycarboxylate superplasticizers with enhanced
The interlayer spacing of sodium bentonite increased by 0.2 nm after the adsorption of superplasticizer, without significant difference between APC and PCE. A possible mechanism was proposed that the cationic groups can insert into the interlayer of clay by cation exchange, and the intercalation of PEO side chains was inhibited, which is

results show that adaptability of the PCE-2 is better than those of the commercially available 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].

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 Superplasticizer (PCE) For Concrete
Polycarboxylate superplasticizer (PCE), also known as polycarboxylate ether superplasticizer, is a new generation of high-performance concrete admixture. It is a water reducing agent with excellent performance that integrates water reduction, slump protection, reinforcement, shrinkage and environmental protection.
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
- What is a polycarboxylate ether (PCE) superplasticizer?
- Polycarboxylate ether (PCE) superplasticizers have a variety of uses such as improving concrete liquidity and pumping, reducing water-ash ratio, improving crack resistance, improving early intensity and saving cement dosage.
- Does Polycarboxylate ether superplasticizer reduce water consumption?
- As the water reduction rate of concrete mixed with polycarboxylate ether superplasticizeris relatively large, the slump is highly sensitive to water consumption, and water consumption must be strictly controlled during use.
- What is polycarboxylate superplasticizer for sale in chemate?
- Compared to traditional polycarboxylic acid powder water-reducing agents, the polycarboxylate superplasticizer for sale in Chemate is produced by a special process. So that the carboxylic acid groups aren’t destroyed during the powder manufacturing process, thereby retaining the slump retention of the original liquid mother liquor.
- 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 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.
