【Abstract】 The concrete superplasticizer has many technical characteristics such as reducing water volume and improving the workability of concrete. The latest developed high effective water reducer has also workability, favorable to enhance the construction quality of concrete, so the superplasticizer is the indispensability element of modern concrete. In this paper, the development conditions of superplasticizer and its influence to the concrete are summarized. The technical characteristics and the producing theorem of superplasticizer are introduced.更多还原
