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 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.
Poly(carboxylate ether)-based superplasticizer achieves workability
While neat CAC was almost unworkable after 1 hour, with the addition of only 0.4% of the optimized superplasticizer, 90% fluidity retention was achieved. Introduction CAC is the cement of choice...
Peramin CONPAC - PolyCarboxylate Ether (PCE) polymers
Superplasticizers are high-range water reducing additives used when the dispersion of particles in suspension is required to modify mortars and concrete. They allow for a large reduction of the water content without affecting their workability, shorter setting time, lower shrinkage and higher mechanical strengths.
The Effect of Various Superplasticizers on Ultra High
Ultra-High Strength Concrete (UHSC) is a high-strength and highly ductile material formulated to provide compressive strengths exceeding 130 MPa. UHSC materials typically have a very low water-to-cementitious ratio (w/cm), which requires the use of superplasticizers, also known as High Range Water Reducing Admixtures (HRWRA), to disperse the
- 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 polycarboxylate superplasticizer (PCE)?
- Polycarboxylate Superplasticizer (PCE) represents the latest innovation in concrete admixture technology. Unlike traditional superplasticizers, PCE offers unparalleled control over concrete's rheological properties, making it essential in the production of high-performance concrete.
- Do Polycarboxylate ether/ester superplasticizers affect concrete performance?
- Polycarboxylate ether/ester (PCE) superplasticizers are widely used due to their molecular structural designability, low dosage and high efficiency. However, their high sensitivity and strong interactions with clays in concrete reduce their dispersion and water-reduction capability, which can affect the performance of concrete seriously.
- How to use polycarboxylate superplasticizer?
- Our product technology and the production equipment of this system have obtained numerous national patents in China. Polycarboxylate Superplasticizer must preferably be added to the mixing water and in case of ready mixed concrete where the product can be added on fresh concrete and in a mixing truck.
- 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.
- 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.
