Granite, weathered granite, gnesis, limestone, dolomite, sandstone, shale, mudstone, rhyolite, basalt, and tuff were prepared as slab specimens. Freeze-thaw cycles were repeated 180~300 times under temperatures ranging from -25°C to +30°C, and the changes in weathering patterns and weathering products were observed. As a result, Granite does not have joints or cracks, and instead exhibits granular disintegration and conchoidal shattering on its surface. Gneiss is the most weathering-resistant among those tested, and the released iron only stained the surface and does not cause any changes. The limestone had a few sharp fragments detached, and the dolomite had developed joints along the calcite veins and was completely shattered. Shale and mudstone were the most extreme forms of rocks in a constantly saturated condition. Shale and mudstone were broken into fragments by vertical crack, then horizontal cracks developed along the bedding. In particular, mudstones were completely fractured after developing a polygonal structure around a contraction point. Rhyolite had some granular disintegration and thin films (flake) on the surface, and basalt was rarely weathered except for a few platy-shape debris by tearing or plucking. The tuff developed short, irregular cracks along its boundaries, which separate into a spherulitic aggregates.
