The influence of type and combination of polycarboxylate
High performance self-consolidating concrete (HPSCC) is defined as a type of flowing mixture with high deformability and achieving high mechanical strength as well as with superior durability performances. The design of such concrete is more complicated than that of ordinary concrete.

polyoxyethylene ether) type polycarboxylate superplasticizer is the mainstream polycarboxylate superplasticizer in the market because of its outstanding water reducing performance [3]. The development of TPEG type polycarboxylate superplasticizer process generally passes the laboratory small-scale experiment first.
Polycarboxylate Superplasticizer (PCE) For Concrete
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.

- What is a polycarboxylic superplasticizer (PCE)?
- Polycarboxylic superplasticizers (PCEs) have been regarded as key materials for high-performance concrete preparation due to their low dosage, good slump maintenance, and high water-reducing rate [1, 2].
- What is polycarboxylic ether superplasticizer?
- 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.
- What is a polycarboxylate superplasticizer?
- A series of polycarboxylate superplasticizers (PCEs) with varying carboxyl densities were synthesized at room temperature using the molecular design principle. The PCEs molecular structure was determined using 1 H NMR and MALDI-TOF. The paste fluidity, foam stability as well as other performance of PCEs obtained was also tested.
- What is TPEG?
- TPEG is a kind of main raw material (polycarboxylate ether monomer) for producing high performance water reducing type and slump retention type polycarboxylate superplasticizer, it is produced with isopentenol and ethylene epoxide as main raw materials.
- Can hpeg be used as an alternative to TPEG?
- HPEG has long been widely used as an alternative to TPEG. In this study, a new high-performance HPEG-type polycarboxylate superplasticizer PCE-A was synthesized by using H 2 O 2 and sodium hypophosphite/Vc redox initiation system to provide free radicals under aqueous polymerization conditions with HPEG and acrylic acid as the main raw materials.
- What are structural changes in polycarboxylate superplasticizer (PCE)?
- 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 the compatibility of Portland cement and so on.
