摘要
Abstract
The construction quality of grout sleeve splicing of rebarsis the key factor of reliability of assembled monolithic precast concrete structure.To research the effects of ambient temperature and curing period,90 specimens were tensioned monotonically.It shows that the higher ambient temperature the higher ultimate bearing capacity show the grouting coupler specimens.Besides,when the compressive strength of the grout is lower than 62.5 MPa,the compressive strength of the grout and the ultimate bearing capacity of the specimens have a linear relation.However,when the compressive strength of the grout is higher than 62.5 MPa,it has little influence on the performance of grouting coupler.关键词
