ABSTRACT
Poured concrete will began to harden and we may need to conduct some tests and measurements to ascertain the quality of concrete, to settle any disagreement between the contractor and the owner or the consultant, or to verify parts of the construction. The quality control inspector should be able to detect the quality of hardened concrete through the use of nondestructive testing. The inspector should choose the method that is economically feasible, based on the structure condition and system. The tests should be selected based on the condition of the structure and the location of the member that will be tested and the test should provide accurate results (Table 6.1).
