Newfoundland's First Arch Dam Construction Versus Climateby H. L. Boggs,
D. M. Besaw,
P. C. Helwig,
Abstract: Paradise River arch dam is located in a narrow box canyon about 50 m deep and less than 10 m wide at streambed. It is a thin arch dam, especially sensitive to temperature loads, thus contraction joint grouting at the correct concrete temperature was critical. Concrete construction was undertaken during the late summer and fall of 1988 and required dealing with problems of mix design, placing temperature, natural cooling and contraction joint grouting.
