Use of infrared thermography for concrete strength assessment with different overlay

Concrete has been used in construction for more than a century now and have it advantages and disadvantages. A number of existing structures exhibit distresses and lack of load‐carrying capacity. Repair and strengthening of existing structures are in fact among the biggest challenges civil engineers...

There are different colour produced by IRT image, where the object dominant in temperature produce brighter colour. The effectiveness of the IRT to detect the colour changes produce by the beam with different grade and to determine it strength cannot be achieved because IRT unable to produce colour changes on the beam. Therefore the IRT test is less effective compare to the UPV during the determination of concrete with different grade and also it strength. 2017-06 Undergraduates Project Papers NonPeerReviewed application/pdf en http://umpir.ump.edu.my/id/eprint/20896/1/Use%20of%20infrared%20thermography%20for%20concrete%20strength%20assessment%20with%20different%20overlay-Table%20of%20contents.pdf application/pdf en http://umpir.ump.edu.my/id/eprint/20896/7/Use%20of%20infrared%20thermography%20for%20concrete%20strength%20assessment%20with%20different%20overlay-Abstract.pdf application/pdf en http://umpir.ump.edu.my/id/eprint/20896/13/Use%20of%20infrared%20thermography%20for%20concrete%20strength%20assessment%20with%20different%20overlay-Chapter%201.pdf application/pdf en http://umpir.ump.edu.my/id/eprint/20896/19/Use%20of%20infrared%20thermography%20for%20concrete%20strength%20assessment%20with%20different%20overlay-References.pdf Mohammad Iskandar Halimie, Abd Halim (2017) Use of infrared thermography for concrete strength assessment with different overlay.
