A Testing Method of High Speedy Carbonation of Concrete

摘要

The present invention uses an air compressor and vacuum pump through a hole formed on one side of the vessel into the concrete specimen by spraying water, and is via a through-hole formed on the other side of the vessel by injecting carbon dioxide (CO ₂ ) to provide a method for promoting carbonation of the concrete test specimens. At this time, the water may be used. 0 ~ 50 range, the water jet may be used to control the diameter of the nozzle outlet by 10 ~ 200 range, CO in the injection of carbon dioxide vessel ₂ This may be used to adjust the internal pressure to 0.1 to 900 Torr (torr) range. Here, the water injection may be injected by a per 1 ~ 2 , when the injection time is adjusted via the gauge due to the size of the specimen, and when injecting the set pressure through the pressure gauge on the inlet side of the carbon dioxide injection well. Of course, the injected water may be recovered and reused or disposed of through tonggu after testing the lower end.
