Synthesis and Properties of a Polycarboxylate
Polycarboxylate superplasticizers (PCEs) are comb-shaped polymers with an anionic backbone and several nonionic pendant chains, which typically are comprised of polyethylene glycols. In this study, the synthesis of a new type of superplasticizer is presented, which does not exhibit the typical comb-shaped form of PCEs but is built up from a linear polyetheramine and a hyperbranched
Polycarboxylate Superplasticizers | Supercizer PCE | Fritz-Pak
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 Superplasticizers - Concrete Construction
Very often, a superplasticizer will be formulated with a blend of two or more PCEs to achieve a combined performance of both early strength and long slump life. Researchers will continue to actively manipulate PCE polymer structure to meet the ever changing material and construction requirements.
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 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.
- 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.
- 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 powder used for?
- Polycarboxylate superplasticizer powder has excellent adaptability, especially suitable for sulphur-aluminum, high-aluminum and gypsum systems. It can be widely used in various products systems such as dry mortar and concrete.
- 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.
- 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.
