The use of carbon dioxide to preserve cementitious materials has been a long time ago. People have used the atmospheric carbon dioxide to preserve lime for nearly a thousand years. The content of carbon dioxide is very important. It plays a very important role in the completion of conservation work. Carbon dioxide detectors, carbon dioxide meters, etc. are all special instruments that measure the amount of carbon dioxide in a particular environment. Carbon dioxide curing concrete is a technique that uses carbon dioxide to chemically react with cement clinker components to accelerate curing. Carbon dioxide curing can cause rapid hardening and strength development of concrete products, and its main reaction product: calcium carbonate has good stability. Young believes that the protective effect is mainly due to chemical reactions.
We accept

Young et al. used carbon-conserving concrete with a very low water-to-rubber ratio. Sorochkin added supercritical carbon dioxide to the concrete during the mixing process. However, the degree of reaction between carbon dioxide and concrete was limited, and the products after the reaction did not meet satisfactory performance requirements. , And the low water-binder ratio and gas pressure limitations make it difficult for concrete carbon dioxide curing technology to be used in actual production. By pre-conserving ordinary block concrete to control the moisture content in the block concrete, the carbon dioxide is promoted. Reacts with cement clinker minerals to achieve a high degree of carbon dioxide curing and desired properties.
Carbon dioxide detector, carbon dioxide monitor in manual mode, the working mode is to press a once, it can record the time and the various environmental parameters. You can set the interval time to automatically record, press the stop button to stop at any time. After the data collection is complete, the data can be sent to the computer. The software will automatically generate curve graphs that can be printed and processed. Visible carbon dioxide detector, carbon dioxide meter is able to contribute to the maintenance of cementitious materials can not be underestimated the energy.
