Introduction With the rapid development of architectural technology, high performance concrete is extensively applied in civil engineering such as industrial and civil architecture, roads, bridges, hydraulic engineering.
So the concrete superplasticizer become the indispensable additives for high performance concrete, and the water reducing effect of the superplasticizer also becomes the issue to which the engineering and technical personnel pay great attention.
