Investigation of Nonmetallic Waterstops. Report 9. Final Report of Effect of Exposure,

Abstract

Samples of natural rubber, synthetic rubber, and polyvinyl chloride (PVC) waterstops (stressed, unstressed, and embedded) were exposed at Treat Island, Maine; at St. Augustine, Florida; near St. Louis, Missouri; near New Orleans, Louisiana; and at Jackson, Mississippi, to determine the effect of various exposure conditions. The exposure conditions were as follows: (a) exposure to freezing and thawing in a marine environment, (b) exposure to wetting and drying in a warm marine environment, (c) outdoor exposure in a moderate climate, (d) indoor exposure (air without sunlight), (e) exposure in a weak solution of sodium and magnesium sulfate, (f) exposure to cold contaminated water, (g) exposure to cold fresh water, (h) exposure to warm contaminated water, and (i) exposure to warm fresh water. The samples were exposed during the period 1957-1959, and visual inspections of the exposed specimens were made periodically.
