Abstract:This paper outlines the testing program developed for the Raftsundet Bridge, the first bridge in Norway that utilized pumping for placement of lightweight concrete. It reports the results from parallel testing of both normalweight and lightweight concrete performed during construction of this bridge. This paper also presents a discussion of the economics of using high performance lightweight concrete on the Rugsund Bridge. It also describes the Sundoy Bridge, the second bridge in Norway to utilize pumping for lightweight concrete placement. These projects confirm that high strength lightweight concrete is an economical, efficient construction material for long span bridges. While lightweight concrete may cost more per cubic yard than normalweight concrete, the structure may cost less as a result of reduced dead weight and lower foundation costs (1).
