Progresses in Synthesis of Polycarboxylate Superplasticizer - Hindawi
The prerequisite to synthesize PCE was to prepare new macromonomers with controlled molecular mass, adjustable hydrophilic-lipophilic groups, long-chain alkyl groups, and large terminal hydroxyl groups as well. Structural modifications in the molecular scale of polycarboxylate superplasticizer (PCE) would lead to changes in properties of dispersion and water retention as well as enhancement in

Synthesis and Properties of a Polycarboxylate Superplasticizer with a
Polycarboxylate superplasticizers (PCEs) emerged as one of the most important superplasticizers for concrete due to their superior performance. (1,2) Compared to other products like polycondensates, they fluidize cement even at low water to cement ratios, require relatively low dosages, and exhibit a long slump retention capability. (35) The
Synthesis of polycarboxylic ether superplasticizers based on the high
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.
Effectiveness of Thermal Stimulation of Superplasticizers on Fresh
Polycarboxylic acid-based superplasticizers are used in various types of concrete work. Wide variations in environmental temperatures are known to affect how well chemical admixtures perform as superplasticizers, influencing the properties of the concrete. However, little has been reported on changes in performance caused by thermal variations. Previous studies have reported that heating
- How are polycarboxylate superplasticizers synthesized?
- A series of polycarboxylate ratios ratios of different monomers, and adjusted reaction processes. A series of polycarboxylate superplasticizers of different superplasticizers monomers, and (PCEs) (PCEs) was adjusted was synthesized synthesized using reaction using allyl processes.
- What is Polycarboxylate ether/ester (PCE) superplasticizer?
- 1. Introduction Polycarboxylate ether/ester (PCE) superplasticizer is a new generation of superplasticizer following the development of poly (naphthalene sulfonate) (PNS), poly (melamine sulfonate) (PMS) and acetone formaldehyde sulfite (AFS) superplasticizers.
- What are structural changes in polycarboxylate superplasticizer (PCE)?
- Structural modifications in the molecular scale of polycarboxylate superplasticizer (PCE) would lead to changes in properties of dispersion and water retention as well as enhancement in the compatibility of Portland cement and so on.
- What is polycarboxylic ether superplasticizer?

- What is the molecular structure of modified polycarboxylate superplasticizer (PCE-P)?
- The FTIR results revealed that the molecular structure of the modified polycarboxylate superplasticizer (PCE-P) comprised sulfonic acid, carboxylic acid, and polyepoxyethane vinyl groups, exhibiting a comb-like molecular structure.
- Can polycarboxylate superplasticizers adsorption and dispersion properties of PCE-P?
- Application Limited research has been conducted on the adsorption and dispersion properties of PC when combined with various polycarboxylate superplasticizers. PCE-P with a consistent main chain length but varying side chain lengths was synthesized by controlling the molar ratio of macromonomer to methacrylic acid.
