Based on the guide by the SIP and the material by the Tohoku Regional Development Bureau, we decided to apply multiple protection to reduce LCC and to reduce the risk for deterioration reasonably and efficiently in RC floor slab of Shin-yanagibuchi bridge. For constructing of the actual RC floor slab of the bridge, we confirmed the composition, physical properties and workability of concrete at each stage of laboratory test mixing, real machine test mixing, and test construction.
