The behaviors and economies of PCA SP-blended concrete were investigated. Inclusion of PCA SP improves the initial fluidity and fluidity preservation of concrete. Utilizing PCA SP increased the air content and bleeding water rate and prolonged the setting times of concrete, which have a negative effect on the early-age properties of concrete.
The hydration rate, hydration products, and pore structure of the concrete containing different functional polycarboxylic acid superplasticizers were analyzed by means of mercury intrusion test
- What is polycarboxylate superplasticizer?
- 1. Introduction The polycarboxylate superplasticizer is characterized by low dosage requirements, a high water-reducing rate, excellent slump retention performance, and strong designability and environmental friendliness during the production process, making them the most widely used admixture in modern concrete , , .
- What is polycarboxylic ether superplasticizer?
- 1. Introduction Generally, polycarboxylic ether superplasticizer (PCEs) have excellent properties of high water reduction and high slump retention capacity, and they are widely used in engineering , , , . In the synthesis of PCEs, the types of macromonomers are extremely important.
- Are Polycarboxylate ether superplasticizers a good water reducing agent?
- High-performance plasticizers represented by polycarboxylate ether superplasticizers (PCEs) as the third generation of water reducing agent, possess high water reducing rate, low dosage, good dispersion performance, as well as good slumping performance, low concrete shrinkage rate, and adjustable molecular structure.
- Why do Polycarboxylate ether superplasticizers entangle?
- However, too high feed ratio may result in entangling due to the long molecular backbone, too low feed ration can give rise to entangling due to the dense side chains. These evidences are helpful for designing and synthesizing well-defined polycarboxylate ether superplasticizers.
- Are Polycarboxylate ether superplasticizers based on RAFT polymerization?
- In summary, a series of novel polycarboxylate ether superplasticizers with well-defined structures were synthesized by RAFT polymerization. The feed monomer ratio, reaction time and temperature are related to the composition and structure of RPCs, further influence the dispersion performance and adsorption capacity of RPCs.
- Which chain transfer agent is used in polycarboxylate superplasticizer?
- The selected chain transfer agent is 3-mercaptopropionic acid. Under conditions where the acid-ether ratio is 4.0:1, the reflection temperature is 35°C, the sulfonic acid content is 16.0%, and the initiator dosage is 1.0%, with all other reaction conditions held constant, polycarboxylate superplasticizer were synthesized.
