That's definitely impossible. The temperature of -27 degrees is already a low-temperature cold storage, and the tiles in the low-temperature cold storage will definitely explode in a short time. If you go to the design institute, they will definitely make insulation layer and gas barrier, and if you are elegant, they will also make thermal circulation system. The concrete part above is now designed as a wear-resistant+curing agent floor. Now this scheme is feasible. The only regret is that the curing agent brands at home and abroad (such as Sika, BASF, Cooper, Shibei, etc. Without the anti-crack function, the problem of cracks in the floor will be very serious after it is finished. As far as I know, Mo Ze has a protection system and is also an efficient curing agent. It has been patented in the United States and approved by the United States Department of Agriculture for use in the food processing industry in the United States. It was introduced to China a few years ago. This curing agent is very special. It consists of two materials to form a system. One is Moser 2000, and its function is 1: After use, concrete can obtain the function of permanent freeze-thaw cycle. 3: Low temperature resistance, minimum resistance to -60 degrees. Two: Moser 2000SF liquid curing agent, also known as curing agent, function: 1: excellent compactness 2: super wear resistance, impact resistance, heavy load resistance, excellent anti-skid performance and quick deicing.
Therefore, wear-resistant and Moser curing agent should be the best choice for the ground of low-temperature cold storage, that is, Moser curing agent is imported, which has many functions that other curing agents do not have, and may be a bit expensive, but after using this curing agent, the built-in thermal circulation system of concrete can be omitted, and it is still cost-effective in the long run.
