[0020] 1. Compared with the existing technology, the utility model connects the high-strength steel pressure barrel with the sealing cover through the connecting parts around it to ensure the airtightness of the cementitious material mixing environment. The air in the mixing system is extracted through the vacuum pump connected to the air outlet, and then the system is filled with carbon dioxide gas to achieve a pure carbon dioxide mixing environment.

[0021] 2. This utility model can adjust the concentration of carbon dioxide introduced to achieve different temperature gas reaction conditions. The pressure gauge on the top of the sealing lid can monitor the pressure changes in the barrel in real time.
