Abstract:
Nonprestressed reinforced concrete liquid containment structures—in particular, noncircular tanks—often exhibit vertical and diagonal cracks that are aesthetically objectionable. More importantly, cracks could result in loss of stored liquids, leakage of hazardous materials, concrete deterioration, and corrosion of reinforcing bars. Such cracks, however, are seldom indicative of structural failure. This TechNote reviews the methodology of repair in liquid containment structures.
