Abstract:
Synopsis-This report is a companion to ACI 210R. It contains a series of case histories on hydraulic structures that have been damaged by erosion from various physical, mechanical, and chemical actions. Many of these structures have been successfully repaired. There were many examples to select from; however the committee has selected recent, typical projects, with differing repair techniques, to provide a broad range of current expe-rience. These case histories cover only damage to the hydraulic surfaces due to the action of watel; waterborne material, or chemical attack of concrete from fluids conveyed along the hydraulic passages. In addition to repairs of the damaged concrete, remedial work frequently includes design modifications that are intended to eliminate or minimize the action that produced the damage. This report does not cover repair of concrete damaged by other environmental factors such as freeze-thaw, expansive aggregate, or corroding reinforcement.
