Title:
CEMENT-BASED GROUTING MATERIAL FOR X-RAY DETECTION OF GROUTING COMPACTNESS, AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/231058
Kind Code:
A1
Abstract:
A cement-based grouting material for the X-ray detection of grouting compactness, and a preparation method therefor. The preparation method comprises the following steps: a cementing material component, an aggregate component, an admixture component, an additive component and an X-ray absorption component being comprised, wherein the cementing material component is ordinary Portland cement, the aggregate component is river sand or machine-made sand, the admixture component is silica fume, and the X-ray absorption component is one or several metal oxide powders and a graphene material. The cement-based grouting material for the X-ray detection of grouting compactness and the preparation method therefor are rational in terms of design, and one of a tungsten oxide heavy metal oxide powder and a lead oxide heavy metal oxide powder or a combination thereof is used as an X-ray photon absorption component, such that the X-ray attenuation coefficient of the grouting material is increased, the gray value difference between a dense portion and a cavity portion of grout is enhanced, and the problem of a small X-ray absorption capacity difference between the dense portion and the cavity portion of traditional grout can be solved.
