Reasons for the formation of stone freeze-thaw phenomenon

The main reason for the freezing and thawing of stone is due to one source-water. When the capillary stone cutter pores of the stone absorb the corresponding water, the water in the stone will start to freeze once the temperature drops below 0°C.

Generally speaking, substances follow the law of "heat expansion and contraction", while water does the opposite. The density granite cutter of water is at its maximum at 4°C, and water molecules are mobile and run independently. When the temperature of the water decreases from 4°C to 0°C, the water molecules in the ice marble block cutter are arranged in a three-dimensional pattern into an unusually loose form. This structural form actually leaves many "holes", but the density decreases instead. Experiments have shown that when 1 cubic meter of water freezes, its volume will increase to 1.11 cubic meters.

Therefore, when water enters the pores or crevices of the edge cutting machine natural stone, it becomes frozen and increases in volume, thereby swelling the pores or crevices of the natural stone. Then, the natural stone absorbs more water, and the pores or crevices are further enlarged. This vicious circle, Which quarry mining machine eventually led to the fragmentation of natural stone.
