Concrete Structure Condition Rating in Buildings with Non-Destructive Testing

Abstract

Concrete damage on building is translated as a condition change from concrete quality. The damage that is referred to can be in the form of physical change or concrete quality downgrade on a building. This change can be caused by several reasons, such as implementation error, building overload, building function change, inadequate building maintenance, natural condition, and natural disaster. Concrete damage condition on buildings can be identified by performing a condition rating assessment. Condition rating assessment Is determined based on non-destructive examination. Assessment analysis results show the concrete structure condition and the action that must be done.

Estimation of present-day strength of concrete for a 40-yearold building from non-destructive tests: A case study

“…Poorarbabi et al [17] examined the conversion factors between NDT of cube and cylindrical concrete specimens. A concept of condition rating was suggested by Wiyanto et al [18] based on analysis of the results of NDT. Estimate of conservative strength for existing structure from NDT results was discussed by Dauji et al [19], but the data used in the study was pair-wise NDT and PDT results, from which site-specific correlation expressions could be developed.…”
