Researchers developed excellent PCE with higher water reduction, good adaptability, and other good performances. At the same time, they have been trying to broaden sources of raw materials and synthetic processes, reduce the cost of production, and improve the quality of stability step by step.
High-performance superplasticizer based on chitosan - ScienceDirect
7.1. Introduction. A water-reducing agent is an important and indispensable ingredient of modern concrete. It helps to produce fresh concrete that has a high fluidity and low water-to-cement (w/c) ratio; in addition, it can notably increase the mechanical strength of hardened concrete at a lower cost (Plank et al., 2008, Petit et al., 2010).
Superplasticizer: Types, Advantages & Disadvantages - Constructionor.Com
Superplasticizer is also known as high range water reducers, it produces extreme workability flowing concrete. It has the efficiency of dispersing fine-grained particles like cement, fly ash, ground granulated blast furnace slag, and silica. They increase slump for ease of placement, creates the denser and more durable concrete.

- What is PCE superplasticizer?
- PCE superplasticizer is a high-performance water reducing agent that integrates many functions such as high water reduction, high collapse retention, reinforcement, shrinkage, and environmental protection. It is also an ideal admixture for preparing high-strength and high-performance concrete.
- What is high performance polycarboxylic acid water reducing agent?
- The use of high performance polycarboxylic acid water-reducing agents is especially important to meet the demand for high performance concrete in various projects. Therefore, the development and utilization of high performance polycarboxylic acid water reducing agents and other concrete additives has become a research hotspot [1-6].
- 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
- Does water reducing polycarboxylic acid superplasticizer J have better water-reducing and slump retention properties?
- The fluidity of sample 3 after 1 h plus 40 min (170 mm) still remains good, and its fluidity loss over time is small (5.9%), which confirms that water-reducing polycarboxylic acid superplasticizer J has better water-reducing and slump retention properties.
- Are polycarboxylic acid water reducing agents better than naphthalene based superplasticizers?
- In terms of rheological and mechanical properties, the cement samples formulated with functional polycarboxylic acid water-reducing agents are more likely to achieve improved rheological properties and higher compressive strength than the cement-based materials containing naphthalene-based superplasticizers.
- What is the best synthesis process for high performance polycarboxylic acid water reducing agent?
- 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.
