Synthesis and Properties of a Polycarboxylate
Polycarboxylate superplasticizers (PCEs) are comb-shaped polymers with an anionic backbone and several nonionic pendant chains, which typically are comprised of polyethylene glycols. In this study, the synthesis of a new type of superplasticizer is presented, which does not exhibit the typical comb-shaped form of PCEs but is built up from a linear polyetheramine and a hyperbranched
Progresses in Synthesis of Polycarboxylate Superplasticizer
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
Superplasticizer - an overview | ScienceDirect Topics
A silicone water-repellent admixture has been found to be effective as a superplasticiser apart from being a water-repellent admixture for rammed earth materials. Silicone is used as a release agent and workability or compaction enhancement agent for many uses.
Polycarboxylate Superplasticizer Powder & Liquid for Concrete
Polycarboxylate superplasticizer (High Slump Retention) is clear transparent liquid. It keeps the slump of concrete well, and can prolong the slump retention time of concrete. What’s more, PCE superplasticizer also shows great performance in hot environments. The packing of PCE liquid is 230kg PE drum, 1100kg IBC tank or flexitank.
Polycarboxylate Superplasticizer (PCE) For Concrete
It is a new generation of polycarboxylate ether polymer, which can be used as a superplasticizer for cement-based materials. Polycarboxylate powder is also an excellent dispersing plasticizer for mineral materials such as gypsum and ceramics. 2. High Water Reduction. PCE water reducer is a ready-to-use liquid superplasticizer.
- What are the advantages of polycarboxylate based superplasticizer?
- Low dosage and high water reduction rate. The water reduction rate of polycarboxylate based superplasticizer can be as high as 45%, which can be used to prepare high-strength and high-performance concrete. Small loss when slump is light.
- What is polycarboxylate superplasticizer (PCE)?
- As one important auxiliary, superplasticizers have attracted lots of attention in the concrete and building materials field. Specially, polycarboxylate superplasticizer (PCE) has been widely applied due to its relatively low doping amount, high water reducing rate and environmental friendliness property.
- 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.
- 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.
- 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.
- 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.
