RESEARCH ON MECHANICAL PROPERTIES AND GROUTABILITIES OF GROUTED MORTISE-TENON JOINTS FOR PREFABRICATED STRUCTURES
Introduction: The paper addresses grouted tenon-and-groove joints in the prefabricated structure of Changchun subway station. For the first time, grouting of prefabricated structure joints with organic epoxy grouting material is analyzed. Purpose of the study: We aimed to make sure that an organic epoxy grouting material can be injected into the joints uniformly and in full and conducted its experimental study. To establish the applicability of the epoxy grouting material in the prefabricated structures, we studied the mechanical properties of the epoxy grout and its adhesive properties in relation to concrete. Methods: In the course of the study, we used a set of test equipment and an independently developed method. Results: High-quality grouting can be guaranteed at an injection pressure of 0.4 MPa and a temperature of 5–10°C. The relationship between the slurry flow rate and time was fit according to the experimental data at 5 and 10°C. The optimal quartz powder ratio was determined at the level of 1:0.6–1:0.8, and the optimal quartz powder particle size (D50) was determined at the level of 18–25 μm. The results of the study can provide references for similar projects in the future.
