Abstract:In order to study the strength reduction caused by delamination, single-gap and double-gap specimens were made, and a uniaxial compressive strength (UCS) test was used to analyze the relationship between filling interval time (FIT) and UCS of single and double-spacing specimens. Based on the cement hydration reaction theory and damage mechanics, the influence mechanism of the FIT on backfill strength was studied. The test results show that the UCS of double-interval backfill is affected by two filling interval… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
