Cement-based grouting material for X-ray detection of grouting compactness and preparation method thereof
The invention provides a cement-based grouting material for X-ray detection of grouting compactness and a preparation method thereof, the preparation method comprises the following steps: the cement-based grouting material comprises a cementing material component, an aggregate component, an admixture component, an admixture component and an X-ray absorption component, the cementing material component adopts ordinary Portland cement, the aggregate component adopts river sand or machine-made sand, and the admixture component adopts an additive component. The cement-based grouting material comprises an admixture component and an X-ray absorption component, the admixture component adopts silica fume, and the X-ray absorption component adopts one or more metal oxide powder and a graphene material. One or a combination of tungsten oxide powder, lead oxide powder and heavy metal oxide powder is adopted as an X-ray photon absorption component, the X-ray attenuation coefficient of the grouting material is increased, the gray value difference between a grouting dense part and a cavity part is enhanced, and the problem that the X-ray absorption capacity difference between the traditional grouting dense part and the cavity part is small can be solved.
本发明提供一种用于X射线检测灌浆密实度的水泥基灌浆料及其制备方法，包括如下步骤，包括胶凝材料组分、骨料组分、掺合料组分、外加剂组分和X射线吸收组分，所述胶凝材料组分采用普通硅酸盐水泥，所述骨料组分采用河砂或者机制砂，所述掺合料组分采用硅灰，所述X射线吸收组分采用一种或几种金属氧化物粉末和石墨烯类材料，该用于X射线检测灌浆密实度的水泥基灌浆料及其制备方法设计合理，采用氧化钨、氧化铅重金属氧化物粉末中的一种或其组合作为X射线光子吸收组分，提高灌浆料的X射线衰减系数，增强灌浆密实部分和空洞部分的灰度值差异，能够解决传统灌浆密实部分与空洞部分X射线吸收能力差异小的问题。
