ALKALI-SILICA REACTION CAUSES CONCRETE PIPE TO COLLAPSE

A case is described of catastrophic failure of a strucuture caused by alkali-silica reaction, and it is used to show that the limitations of concretes subject to adverse reactions must be considered during design and construction, including the possible interaction of several processes of deterioration. The failure was the collapse of a crown segment of a 36 inch diameter, 5 inch thick, standard reinforced concrete pipe installed as a drain line to a holding pond. The details are described of the field investigation, the petrographic examination, and the cause of failure. The case described is an extreme example, but it demonstrates that the alkali-silica reaction can be strong enough to produce a catastrophic failure. It is noted that actual service conditions of an installation must be ascertained and compared carefully to the allowable operating conditions of the system selected for the design.
