Polycarboxylate Superplasticizer (PCE) For Concrete - Kingsun Chemicals

PCE water reducer is a ready-to-use liquid superplasticizer. It is light yellow in appearance. Besides, it can be completely water easily. 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.

Low-cost synthesis of high-performance polycarboxylic ether by Co2

As a new type of high-performance water-reducing agent, polycarboxylate ether (PCE) has excellent properties such as small dosage and high water reduction rate. However, it is still necessary to develop a synthetic process to improve the performance of PCE at a low cost.

polycarboxylate-based water reducing admixture

Polycarboxylate-based water reducing admixture

Polycarboxylate-based water reducing admixtures (PCE) are widely used in concrete technology as they have superior properties such as ease of molecular structure change, high dispersing and water reduction capacity. Besides these positive effects, PCEs show a high sensitivity to clay particles. Surface adsorption and intercalation of PCEs with clays reduce their dispersing and water reduction ...

adsorption properties of polycarboxylate ether-based high range water

Adsorption properties of polycarboxylate ether-based high range water

1. Introduction. Adsorption is commonly described as a surface phenomenon in which dissolved particles bind to the top layer of the solid surface [1].It is known that the spreading performance of polycarboxylate-based high range water-reducing admixtures (PCE), also known as superplasticizer, in cement paste is directly related with the adsorption behavior on the cement particle surface [2], [3].

synthesis and characterization of a high performance polycarboxylic

Synthesis and characterization of a high performance polycarboxylic

The best synthesis process for high performance polycarboxylic acid water reducing agent under room temperature using polyether TPEG is as follows: acid-ether ratio is 3.0:1, dosage of dibasic ester is 2.8% of the monomer, dosage of initiator is 0.35% of the monomer, dosage of chain transfer agent is 0.35% of the mass of the monomer.
