Device and method for carbonizing and curing porous concrete through flow method
The invention discloses a device and a method for carbonizing and curing porous concrete by a flowing method. The device comprises a carbonizing box, a gas circulating pump and a CO2 gas cylinder, a gas dryer, a gas flow meter and a CO2 concentration detector are arranged on a connecting pipeline of the carbonization box and the gas circulating pump; a pressure gauge and a temperature and humidity detector are mounted on the carbonization box, and the temperature and humidity detector monitors and records temperature and humidity data in real time through a computer; the device can simulate gas sources with different concentrations and carbonization curing of various porous concrete, and the gas circulating pump can realize bidirectional circulation and exhaust. According to the device, gas flowing and carbonization curing of porous concrete are combined, CO2 gas diffusion is accelerated, calcium carbonate is rapidly generated, the CO2 storage speed and storage amount of a cement-based material are remarkably increased, meanwhile, gas circulation takes away water vapor, the pre-curing process is saved, the carbonization curing period is shortened, and the energy consumption is reduced. The defects of long maintenance time, insufficient carbonization and insufficient economic benefits of conventional carbonization are overcome, and the method has a wide application prospect.
本发明公开了一种流动法碳化养护多孔混凝土的装置及方法，该装置包括碳化箱、气体循环泵、CO2气瓶；碳化箱与气体循环泵的连接管路上设置有气体干燥器、气体流速计以及CO2浓度检测计；碳化箱上安装有压力表以及温湿度检测计，温湿度检测计通过电脑实时监测记录温湿度数据；该装置可以模拟不同浓度的气源以及多种多孔混凝土的碳化养护，气体循环泵可以实现双向循环以及排气。该装置将气体流动与多孔混凝土的碳化养护相结合，加速CO2气体扩散，迅速生成碳酸钙，显著提升水泥基材料对CO2的封存速度和封存量，同时气体循环带走水汽节省预养护过程，缩短碳化养护周期，克服了常规碳化养护时间长、碳化不够充分、经济效益不足的缺点，具有广泛的应用前景。
