DEVICE FOR CONCRETE CARBONIZATION

摘要

A device for concrete carbonization is provided to reduce the time for detecting the carbonization of concrete structure remarkably, and obtain mixing ratio of concrete. The device for carbonization(100) of a concrete sample(4) comprises: a pressure vacuum vessel(10) where a plurality of concrete samples are placed on; a vacuum pump(20) connected to the pressure vacuum vessel and discharging the interior air into the outside; a gas supply/discharge unit(30) connected to the pressure vacuum vessel and supplying carbon dioxide gas into the interior of the pressure vacuum vessel or discharging the carbon dioxide gas from the pressure vacuum vessel; and a temperature/humidity control unit(40) for controlling the temperature and humidity in the pressure vacuum vessel according to the measured data on the temperature and humidity, wherein the gas supply/discharge unit comprises three direction valve(34) connected to the pressure vacuum vessel through a gas line(32), a gas storage tank(36) connected to the three direction valve through the gas supply line(35), and an air discharge pump(38) connected to the three direction valve through the air discharge line(37).
