\u003cBR\u003eIn this research, we considered three different mechanisms of frost damage such as frost heave phenomenon, one-dimensional freeze-thaw phenomenon, and closed-type freeze-thaw phenomenon. \u003cBR\u003eWe conducted frost heave experiment and two kinds of laboratory freeze-thaw experiments in order to verify the actual mechanism of the formation of the cracks in the bricks.\u003cBR\u003eFrom the experimental results, it has been confirmed that frost heave phenomenon does not occur in bricks and that cracks does not occur in bricks due to simple one-dimensional freeze-thaw phenomenon.\u003cBR\u003eIn addition, if bricks do not melt completely during repeated freezing leaving some frozen parts and then the bricks refreeze, the melted parts refreeze surrounded by the frozen parts and cracks then appear in the bricks. \u003cBR\u003eIn this research, this mechanism of frost damage has been defined as closed-type freeze-thaw phenomenon.\u003cBR\u003eThis mechanism of frost damage is different from those considered in the past. \u003cBR\u003eIn this article, this new mechanism of frost damage will be described.", "subitem_description_type":
