▎ 摘　　要

NOVELTY - Cement-based grouting material comprises a gelling material component, a bone material component, a blending material component, additive component and X-ray absorption component, where the gelling material component is common silicate cement. The aggregate component is river sand or machine made sand. The admixture component is silicon ash. The X-ray absorption component is at least one metal oxide powder and graphene material, preferably at least one of metal oxide powder tungsten oxide and lead oxide and graphene material. The metal oxide powder is tungsten oxide, lead oxide, iron oxide and nickel oxide. USE - The cement-based grouting material is useful for detecting grouting compactness of X-ray, and also useful in non-destructive detection technology field. ADVANTAGE - The cement-based grouting material has high strength, early fluidity, and strong X-ray absorption performance, has reasonable design, improves X-ray attenuation coefficient, and solves problem small difference in the X-ray absorption capacity between the traditional grouting compact part and cavity part. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparation method of cement-based grouting material for detecting grouting compactness of X-ray. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of formulation of cement-based grouting material for detecting grouting compactness of X-ray (Drawing includes non-English language text).
