Application of Carbon Dioxide Monitor in Cementing Material Maintenance

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.
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.
