Effect of nonionic side chain length of polycarboxylate-ether-based
In this study, three different polycarboxylate-ether-based water-reducing admixtures with the same free nonionic content, anionic/nonionic molar ratio, and main chain length and different side chain lengths were produced. The compatibility of these admixtures with a CEM I 42.5 R-type cement was investigated.
HV6128 - Institute of Physics
polycarboxylate superplasticizer with high water retention. The performance test results show that the product has high water-reducing ratio and better workability when applied to concrete, which can effectively retain the moisture in concrete and ensure the stability of concrete fluidity. 1. Introduction
Polycarboxylate Superplasticizer (PCE) For Concrete - Kingsun Chemicals
The water reduction efficiency of PCE concrete admixture can be up to 25%. It is mainly used in the ready-mixed and precast concrete industries where the highest durability and performance is required. 3. High Slump Retention. PCE-High Slump Retention is a new generation superplasticizer for concrete. It contains polycarboxylate ether polymers
Polycarboxylate Ether Superplasticizer (PCE) for Sale
Kingsun polycarboxylate ether superplasticizers have a great strength effect on concrete. It can improve the impermeability, frost resistance and durability of concrete. Polycarboxylate ethers can make concrete has good liquidity and small slump loss at high temperatures.
Polycarboxylate Superplasticizers - Concrete Construction
Polycarboxylate Superplasticizers. 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
- 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 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 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.
- How to mix polycarboxylate superplasticizer?
- Polycarboxylate Superplasticizer must preferably be added in the mixing water and in case of ready-mix concrete where the product can be added on fresh concrete and in a mixing truck, it is necessary to mix at a high speed for about 6 – 8 minutes. Setting Time Deff.
- 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 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.
