Specification for material selection in cold storage design

Cold storage design materials in addition to heat insulation, moisture-proof materials, a large amount of brick, stone, cement, concrete, mortar, steel and wood.Most of the building materials used in the cold storage are in low temperature and humid environment, so the cold storage design materials have the special requirements of frost resistance and water resistance.The following is for you to share the material selection specifications in the design of cold storage

1. Bricks and stones are required to be marked not less than MU7.5 and not less than 25 when used in cold storage exterior walls; if used in low-temperature storehouse lining walls or internal partitions, they should be not less than MU10, and frost resistance grade should not be lower than 35

2. The common Portland cement has good frost resistance, so the common Portland cement should be preferred for the structure parts in the cold storage room and the freezing room.This is because slag cement frost resistance is also better

3.The cold room is always in a low temperature state, so the moisture in the cold storage foundation is easy to be frozen.This results in the expansion of the land, causing severe deformation of the entire building structure and rendering the cold storage unusable.Therefore, cold storage design materials must have good thermal insulation, so as to ensure that the floor is not affected by low temperature.

  Because of working in low temperature for a long time, especially its periodic freezing and thawing, the building structure is vulnerable to damage.Therefore, the cold storage design materials must have a good frost resistance, to prevent all kinds of adverse cold storage operation phenomenon.
