The effects of structure, composition, and dosage of copolymers on cement particles dispersing capability were studied. The results showed that the properties of superplastisizer were effected by the end group, the esterification, the length and density of graft chain. The superplasticizer has excellent dispersing capability as the length of graft chain was 30.Read More
