The effect of concrete compacted in the horizontal vibration method with a low vibration and a high amplitude was examined by using the color concrete. When the concrete was compacted by this method, it was guessed that the distribution of wave pressure that worked at the impact side of the mould effected the compaction. The wave motion theory of the harbor engineering was applied this study. It was considered that the distribution of wave pressure was controlled as wave height and height at placing of concrete. This theory was verified by using three elements of the height at placing of concrete, the vibration acceleration and the slump. When the height at placing was larger than twice the wave height, compacted was difficult. When the height at placing was smaller than twice the wave height, the wave height was large and surface condition became better along with the vibration acceleration and the slump.
