Synthesis and Effect of Polycarboxylate Superplasticizer with Two Different Molecular Polyethers as Side Chain

Abstract:

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.
