▎ 摘  要

NOVELTY - Graphene oxide clay cement grouting material comprises 50-150 pts. wt. cement, 100-200 pts. wt. clay, 15-75 pts. wt. structural reinforcing agent, 8-15 pts. wt. sodium silicate and 900-1100 pts. water. USE - The graphene oxide clay cement grouting material is useful in ground pre-grouting technology and for rock crack grouting under different formation conditions. ADVANTAGE - The graphene oxide clay cement grouting material has low initial viscosity, good fluidity, high stability, controllable coagulation time, high early plastic strength of the slurry stone body, high compressive strength of stone body and high shearing characteristics. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a preparation method of graphene oxide clay cement grouting material.
