| Abstract: | Composited a kind of underwater nondispersive concrete admixture that do solublelinear macromolecule polymer as tackifier with ASP superplasticizer and seting retard aid. Tested its effect on antidispersive, fluidity self-compact and mechanical property, analyzed microstructure by SEM and MTP. The result shows the admixture has favorable properties in underwater nondispersive concrete. |
