Research progress on polycarboxylate based superplasticizers
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.
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
A polycarboxylate as a superplasticizer for montmorillonite
A novel polycarboxylate superplasticizer (PCE) with a long polyoxyethylene (PEO) chain and a terminal carboxylic group was synthesized from a modified polyether (SAE-IPEG) to increase its performance in cement. The molecular structure of the PCE was characterized by infrared spectroscopy and 1 H nuclear magnetic resonance (NMR) spectroscopy
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.
