Synthesis of polycarboxylic ether superplasticizers based on
Generally, polycarboxylic ether superplasticizer (PCEs) have excellent properties of high water reduction and high slump retention capacity, and they are widely used in engineering [1], [2], [3], [4]. In the synthesis of PCEs, the types of macromonomers are extremely important.

- Which polycarboxylic acid high-performance superplasticizer is best?
- The sustained-release functional polycarboxylic acid high-performance superplasticizer H performs an excellent slump retention function, and the early-strength functional polycarboxylic acid high-performance superplasticizer Z has a significant effect on improving the early and late strength of the mortar. 1. Introduction
- What are polycarboxylate superplasticizers?
- Polycarboxylate superplasticizers (PCEs) have been extensively used in the areas of construction and building; however, the application limitation of PCEs has emerged owing to their sensitivity to clay.
- Why is early-strength polycarboxylic acid superplasticizer important?
- The main reason that early-strength polycarboxylic acid superplasticizer improves the early strength of mortar is that it contains ultra-long side-chain polyoxyethylene functional groups which retard the cement hydration more than the water-reducing polycarboxylic acid superplasticizers J.
- What is the difference between polycarboxylate superplasticizer and hydroxyl group?
- The polycarboxylate superplasticizer, which had suitable graft and block polymers of polyethylene glycol or polyoxyethylene, and a suitable sulfonic group, had small slump loss besides high water-reducing performance. On the other hand, the hydroxyl group at the end of the chain causes gelation easily.
- Do functional polycarboxylic acid superplasticizers affect cement hydration?
- The impacts of the functional polycarboxylic acid superplasticizers on the mechanical properties, rheological properties, and cement hydration of the cement pastes and mortars were investigated.
- Which superplasticizer has better dispersion?
- The structures of these superplasticizers were characterized by gel permeation chromatography (GPC) and Fourier-transform infrared spectroscopy (FTIR). Compared with the common polycarboxylate superplasticizers (O-PCEs), the resultant anticlay PCEs showed better dispersion as far as the fluidity of cement paste and mortar were concerned.
