At home and abroad, research on improving the early strength of polycarboxylate superplasticizers mainly focuses on the following two aspects.
Polycarboxylate water reducing agent has been continuously developed in recent years, and its synthesis conditions have changed from high temperature conditions to low temperature conditions, and its performance has also evolved from a single function of
High performance polycarboxylate water reducer with high dispersibility, good retention performance, low concrete shrinkage and strong molecular structure.In addition, the polycarboxylate water reducing agent does not use formaldehyde and other outstandin
Floor heating using foam insulation, such bubbles due to the thickness will be limited to 3 cm, pipe and foam thickness is only 1.5- 2 cm, to this kind of insulating foam material stays high, in addition to carrying the effect of heat insulation, but also
We have made a brief summary of the development of polycarboxylate water reducers in recent years, focusing on the latest research results of different types of polycarboxylate water reducers.With the continuous improvement of technical requirements for e
The loss of concrete slump is the result of a combination of factors. Understanding the mechanism of concrete slump loss is helpful to understand the role of polycarboxylate superplasticizer in reducing slump loss.
