WebOne of the techniques for improving the detectable defect depth is using pulse phase thermography (PPT). In PPT, temperatures obtained are transformed to phase by Fourier transform. Phase images are constructed from temperature images [1]. Past research has confirmed that it is possible to detect internal defects in concrete using PPT，Fig.1(a ...

WebThe deterioration of concrete structures by seawater is more due to leaching rather than expansion of concrete. Leaching more effects the small concrete structures than expansion while large concrete structures are effected by leaching as well as expansion. WebBatching Of Concrete The process of measuring concrete mix ingredients by either mass or volume and introducing them into the mixer. To produce concrete of uniform quality, the ingredients must be measured …
WebConcrete can deteriorate for a variety of reasons, and concrete damage is often the … WebThe main disadvantages are that results are not obtained immediately; that concrete in specimens may differ from that in the actual structure as a result of different curing and compaction conditions; and that strength properties of a concrete specimen depend on its size and shape.
