Abstract

Abstract

The rebar sleeve grouting connection is often incompletely filled due to unsatisfactory fluidity of grouting material, which needs to be repaired properly. To improve the workability and quality of the grouting repairing construction, a cementitious repairing grouting material (CRGM) was first prepared, then the relevant properties of CRGM and ordinary rebar sleeve grouting material (ORSGM) were experimentally compared. The results showed that the 28 d compressive strength of present CRGM was 96.4 MPa, and early-age vertical expansion rate from 3 h to 24 h was 0.23, which both could meet the index requirements of ORSGM in Cementitious Grout for Sleeve of Rebar Splicing (JG/T 408—2019). Truncated cone fluidity,flow cone fluidity and their 30 minutes retention values of CRGM were obviously much better than that of ORSGM. Comparing with ORSGM at the age of 28 days, the mercury intrusion testing results and cluster analysis of nano-indentation data indicated that the pore structure of CRGM was finer, and the hardness and elastic modulus of the hardened cement paste were higher. The field application also showed that the CRGM had an obvious advantage in groutability, and could be used for repairing construction of the not-full-filled grouting of the reinforcement sleeve grouting connection in the future.
