The findings of the test revealed that 1.5% addition of polycarboxylate ether superplasticizer decrease the compressive strength but appreciate the flexural strength. However, the percentage of...
Superplasticizer
Plasticizers are chemical compounds that enable the production of concrete with approximately 15% less water content. Superplasticizers allow reduction in water content by 30% or more. These additives are employed at the level of a few weight percent. Plasticizers and superplasticizers retard the curing of concrete. [1]
Speciality Concrete Admixture – Polycarboxylate Ether
Polycarboxylate ethers (PCE) contain groups with polyoxyalkylene, especially polyethylene or polypropylene glycol groups as well as carboxylic acid and/or carboxylic acid anhydride monomers. Fairmate is also manufacturing this product. Fairmate’s Brocrete SCC is a specially formulated admixture based on modified carboxylic ether.
- 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 ether?
- Polycarboxylate ether is one of the modern chemical compounds used as a powerful superplasticizer in concrete production. This compound, by reducing water consumption and increasing the workability and strength of concrete, plays a significant role in improving the quality and performance of concrete structures.
- What is polycarboxylate superplasticizer (PCE)?
- Polycarboxylate superplasticizer (PCE), also known as polycarboxylate ether superplasticizer, is a new generation of high-performance concrete admixture.
- What is Polycarboxylate ether (PCE)?
- Polycarboxylate ether (PCE) is an innovative chemical compound widely recognized in the construction industry, particularly in concrete production, as a powerful superplasticizer. Due to its unique molecular structure, this compound can significantly enhance the mechanical properties and performance of concrete.
- How does Polycarboxylate ether improve concrete fluidity?
- Consequently, by separating the cement particles, the fluidity of the concrete is significantly increased, and the water-to-cement ratio is remarkably reduced. Polycarboxylate ether is available in three forms: powdered, slump-retaining, and water-reducing for enhancing concrete fluidity.
- 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.
