| Abstract: | A new type of superplasticizer, i.e. amino-carboxylic-based superplasticizer was developed by adding carboxylic acid group to the molecular structure of traditional aminosulfonic-based superplasticizer. And the influence of factors such as mol ratio of self made sulfonated monomer M, mol ratio of formaldehyde and its dropping speed, as well as the concentration of reaction solution on performance of amino-carboxylic-based superplasticizer were investigated. The results show that the amino-carboxylic-based superplasticizer has high water-reducing ratio, compatibility with cement is superior to naphthalene-based and traditional aminosulfonic-based superplasticizers. |
