Abstract:
Where exposed to frequent freezing and thawing cycles while saturated, concrete in hydraulic structures and on snow-covered flat or nearly fiat surfaces suffers deterioration which requires repair before the strength of the affected structure is seriously impaired. The principal causes of deterioration are enumerated, and several methods of customary repair are discussed, with special mention of the methods employed in making repairs to a number of hydraulic conduits and dams in the high Sierras of California.
