Crack Detection

Concrete materials are meant for supporting structures, building foundations and they act as several load-bearing structures. Over time, due to environmental conditions, and based on the constituent materials used, concrete materials are subjected to a great degree of distress. Corrosion of the reinforcement bars due to chemical influences, uneven base, earthquake, drying shrinkages, and alkali-aggregate reactions are some of the reasons for concrete distress.

For coring rock in borings, three types of core barrels are available—the single wall barrel, the fixed double barrel, and the swivel-type double wall barrel. Describe the advantage that the swivel-type double wall barreloffers for obtaining cores from weathered rock that probably includes cracks, fissures, and seams.
