▎ 摘　　要

NOVELTY - Silane-modified graphene oxide-fly ash based grouting material comprises cement, desulfurized gypsum, fly ash, silane-modified multilayer graphene oxide, alkali-activated material, water reducer, quick-setting agent and water, where the mass ratio of the cement, desulfurized gypsum, and fly ash is 35-45:10-20:40-50. USE - The silane modified oxidation graphene-fly ash-based grouting material is useful for plugging tunnel-rich water-rich crushing belt. ADVANTAGE - The silane modified oxidation graphene-fly ash-based grouting material: utilizes the volcanic ash effect of fly ash and cement and microcrystal nucleus effect to improve the aggregate interface bonding force; and is green and environment-friendly, good fluidity, high, compression strength can be widely applied to fast plugging tunnel wall rock water or rock mass seepage treatment. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of silane modified oxidation graphene-fly ash-based grouting material for plugging tunnel-rich water-rich crushing belt.
