At present, the connection between the steel bars at the node position of the component is mainly connected by grouting sleeves. Grouting sleeve connection refers to the use of sleeves to connect the steel bars at both ends of the prefabricated component, and inject self-compacting and slightly expanding grouting material into the grouting hole of the sleeve. After the grouting material solidifies and hardens, a high-strength connection joint is formed. If the density of the grouting material in the sleeve is insufficient, the grouting sleeve will be damaged by the pull-out of the steel bars under the load, which seriously affects the safety of the structure. Therefore, the density of the grouting sleeve slurry needs to be tested every time grouting is performed.
