Admixtures & Additives - MC-Bauchemie
Superplasticisers based on polycarboxylate ethers (PCE) are essential whenever the application requires a rugged concrete manufactured with a low binding agent content and a low w/c ratio. PCEs are comb-shaped polymers that can be individually adapted as necessary.

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 has become the most important product in the concrete admixture
- What is polycarboxylate superplasticizer (PCE)?
- Polycarboxylate Superplasticizer (PCE) represents the latest innovation in concrete admixture technology. Unlike traditional superplasticizers, PCE offers unparalleled control over concrete's rheological properties, making it essential in the production of high-performance concrete.
- 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.
- 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.
- Does polycarboxylate water reducer reduce cement dosage?
- Save cement dosage. Polycarboxylate water reducer can significantly reduce the amount of cement dosage of concrete and save costs. By adding an appropriate amount of water reducing agent, you can reduce the amount of cement without reducing the strength of the concrete to achieve the purpose of saving costs.
- Why does polycarboxylate lose dispersion capacity in concrete?
- Currently, due to the low-quality of the sand and gravel with high clay content , , more clay is absorbed and intercalated on the side chain of the polycarboxylate superplasticizer. Consequently, its dispersion capacity in concrete may be partially or completely lost , , , , , , , , , , .
