The quality of a visual inspection is affected primarily by; i) The quality of the detector (eye or camera), ii) The lighting conditions, iii) The capability to process the visual data, iv) The level of training and attention to detail Visual inspection is a very simple and basic method; therefore, it is not considered as one of the commonly employed NDT methods. The two phases involved in applying the maturity method to estimate the in-situ strength of concrete are i) Laboratory testing and ii) Field measurement of the in-place temperature history Optical aids such as mirrors, magnifiers and comparators are often used as a tool of visual inspection. The most popular nondestructive test used on concrete structures is the rebound hammer test.
