Causes of freezing and thawing Freezing and thawing occurs mainly in places with relatively cold weather such as the north. When the stone pores absorb enough water, once the temperature drops below 00C, the water in the stone begins to freeze and the volume expands. When the expansion force of the ice block is greater than the structural force of the stone, the stone will crack. This is the freeze-thaw phenomenon. In general, substances follow the law of "heat expansion and contraction," while water is the opposite. The density of water is the largest at 4°C, and water molecules run independently. Water from 4 °C to 0 °C, the temperature is reduced, the water molecules in the ice are arranged in a three-dimensional pattern into an abnormally loose form, this structure form in fact left many "holes", and the density decreased. Experiments have shown that when 1M3 water forms ice, its volume will increase to 1.11M3. Therefore, when the water enters the pores or gaps in the stone, it becomes cold and freezes, and the volume increases. As a result, the pores or crevices of the stone expand, and then, the stone inhales more water, the pores or crevices are further swelled, so that a vicious circle of reversal occurs. Caused the fragmentation of the stone.
Prevention of Freeze-Thaw The main factor in freezing and thawing is water. As long as we prevent water from entering the stone, we can prevent freezing and thawing. Therefore, as long as we use stone curing agent to protect the stone well.
