Select all true statements. Sequential detonation ... 1- provides less confinement when short delay times are used 2-is useful to reduce the size of the rock fragments for massive rock masses 3-O can help to control the effects of zone of weakness in the rock mass 4-has a lesser impact when the rockmass is highly jointed 5-can provide to much confinement with long delay times which can help to spread the muckpile on a larger distance

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.
