The Relationship

The structure of the polycarboxylate superplasticizer (PCE) and the relationship between the structure and the performance of PCE were summarized and analyzed. Based on these results achieved so far, the consensus and the unified opinions were presented while the ambiguous and contradictory points were compared and discussed. Furthermore, the different effect on performance caused by different structure such as side chain length, degree of polymerization, side chain density, functional group were discussed systematically. Finally the existing problems and the measures to be taken in the future were proposed

Main Effect

Water-reducing agent was one of the most important concrete admixtures. Its main effect is to reduce the unit water consumption of concrete, increase strength, but also help to improve the durability, make it easy-to-mix. Water reducer has gone to polycarboxylate superplasticizer which has single side chain generally. A kind of new water reducer by choosing 2500 and 600 molecular polyethers as the side chains has the higher water-reducing effect than the traditional one. It is more than 26 on fluidity retention in 2 hours.

Polycarboxylate Superplasticizer

Abstract Polycarboxylate superplasticizer is synthesised by different acid to ether ratio, which is changing the main chain structure parameters, obtained different microstructures. The effect of different microstructure PCE superplasticizer on the fluidity of cement paste, rheological thixotropy, adsorption capacity and hydration heat are studied. The results show that dispersing performance in cement with acid to ether ratio of 3.5 is the best, the molecular weight and side chain density have rather little effect on the cement hydration process.
