A kind of concrete water reducing agent and preparation method thereof |
| abstract |
The invention provides a concrete water-reducing agent. The water-reducing agent adopts N-hydroxyphthalimide to modify graphene oxide, and then synthesizes graphene-terminated polyoxyethylene ether, which promotes graphene dispersion in concrete. The prepared concrete water reducing agent can improve the fluidity of cement paste, improve the rheological properties of cement-based materials, and improve the mechanical properties after curing. The present invention also provides a preparation method of the water reducing agent. |
