Abstract

Due to an equipment malfunction, too much sand was used in the concrete on the bridge floor placed on August 9, 1994, in Washington County, Project No. BRF-22-2(36)38-92. Freeze-thaw durability testing of cores taken from the concrete in question and the other two concretes not in question was performed. The experimental results indicate that the concrete in question is considered at least as durable and resistant to freeze-thaw damage as the concretes which are not in question. The concrete in question can be expected to function properly for the regular service life of the bridge.
