| Abstract: | A kind of monomer grinding aid was synthesized by hydroxyethylation of ethylenediamine, and the structure of the monomer was proved by IR. The reasults showed that the complex grinding aid had greater effect on grinding and strength of the cement pastes. It improved particle size composition and distribution including increasing the content of fine particle especially of 3 - 30μm particles. It also increased strength of 3 d and 28 d of cement mortar 4.5 MPa and 6.0 MPa. |
