Cement grouting material
The invention provides a cement grouting material, belonging to the technical field of cement-base composite materials. The cement grouting material is composed of 40-50% of PO 42.5R cement, 5-10% of 42.5 rapid-setting sulfoaluminate cement, 40-52% of quartz sand, 3-5% of gypsum, 2-15% of expanding agent, 0.3-2% of additive, 0.01-1% of graphene oxide and 0.05-5% of high-performance fiber. The cement grouting material has the advantages of early strength, high strength, no shrinkage, high flowability and no harmful chemical substances.
