The artificial submerged breakwater to prevent the coastal erosion is required to use the high-capacity and high-density materials due to the corruptions, collapses, floating and destructions by the tidal current, waves and wind. Furthermore, the studies on using the converter slag that is an industrial by-products would both be high-capacity and high-density as an alternative aggregate for concrete to resolve the lack of the natural aggregate in the construction industry is ongoing, however, there is a problem that it causes corruptions by expansion-response from a free lime(Free-CaO) in it.
This study would seek for the way to stabilize rapidly to supplement the general way which is the field heaping. We could make sure that the three stabilizing-rapidly ways found by this study that the converter slag is effective as an alternative aggregate for the marine concrete, in addition, it was proved that these three ways are able to shorten a time for the stabilization compared to a way of the field heaping. Although this study was pretty effective, it seems to require supplementary ways of the stabilization that could not achieve the goals, those are the aimed compression strength and a standard of immersion-expansion(less than 1.5%) prescribed in KSF2535.
