EARLY AGE MONITORING OF CEMENTITIOUS MATERIAL PROPERTIES

摘要：

Early age monitoring of concrete mechanical properties are essential to assure the qualityand the performance of concrete structures. In this paper, a non-destructive one-sidedultrasonic technique, ultrasonic wave reflection method (UWR), was proposed and itscapabilities in monitoring the early age concrete properties at micro and macro structurallevels were briefly reviewed. In addition to the applications of UWR testing, a comprehensivemodeling procedure for estimation of concrete mechanical properties based on the cementpastes properties (measured by UWR method) was also presented herein. Having the manyadvantages over the other in-situ non-destructive testing (NDT) methods, UWR method canbe reliably applied in field to measure the various early age properties besides thecompressive strength of concrete.
