Preparing controlled low strength materials (CLSM) using
To satisfy engineering requirement, the contradiction between flowability and strength of very fine aggregates should be addressed. This paper examines the feasibility of preparing controlled low strength material (CLSM) using excavated waste soils, where polycarboxylate superplasticizer (PCE) is used to improve workability of the materials.
Polycarboxylate Superplasticizer (PCE) For Concrete - Kingsun Chemicals
Polycarboxylate Superplasticizer. Polycarboxylate superplasticizer (PCE), also known as polycarboxylate ether superplasticizer, is a new generation of high-performance concrete admixture. It is a water reducing agent with excellent performance that integrates water reduction, slump protection, reinforcement, shrinkage and environmental protection.
Superplasticizer for High Strength Concrete - ResearchGate
Selecting a high-quality Portland cement and optimizing ... Although the polycarboxylate type superplasticizer was considered to have better compatibility in combination with different kinds
Materials | Free Full-Text | Influence of Pentaerythritol Tetraacrylate
In this work, a crosslinked polycarboxylate superplasticizer (crosslinked-PC) was synthesized via the free radical polymerization reaction. Pentaerythritol tetraacrylate (PETA) was used as the crosslinked agent. A comparative comb-like polycarboxylate superplasticizer (comb-like-PC) was prepared under the same reaction conditions. The dispersion retention capacity, dispersion capability
Superplasticizer: Types, Advantages & Disadvantages - Constructionor.Com
Polycarboxylate superplasticizer- Carboxylated Acrylic-Ester Co-polymers (CAEC): Polycarboxylate superplastics, also known as high-grade water reducers, they are chemicals that are used where well-dispersed particle suspensions are required.
- 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 a polycarboxylate ether superplasticizer?
- The polycarboxylate ether superplasticizer is an additive commonly used in concrete engineering and has a wide range of applications. The PCE based admixture can significantly reduce the amount of cement and improve the fluidity and pumpability of concrete while ensuring the strength and durability of concrete.
- Can polycarboxylate based superplasticizer improve the crack resistance of concrete?
- The polycarboxylate based superplasticizer can improve the crack resistance of concrete. After adding an appropriate amount of water reducing agent in concrete, the internal structure of the concrete can be improved and the contraction and cracking of concrete can be reduced.
- Is star-shaped polycarboxylate a new-type superplasticizer?
- 4. Conclusions The star-shaped polycarboxylate superplasticizer, which can be considered as a new-type superplasticizer, was successfully developed by first “core” then “arm” method (esterification + polymerization) to achieve chemical structure diversity of PCE.
- How to store PCE polycarboxylate superplasticizer?
- The PCE polycarboxylate superplasticizer should be stored in a cool, dry and well-ventilated place, avoiding direct sunlight and rain. At the same time, it should be kept away from fire and heat sources to prevent fire or explosion accidents. Water seepage problem.
- 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.
