我们在研究了煤灰砖水化产物的基础上开始了本专题的工作。 为了在不同CO_2浓度和相对湿度条件下研究CO_2与煤灰制品水化产物的相互作用,我们制作了能同时调节CO_2浓度和相对湿度的炭化设备,调整CO_2浓度的精确度达±1％,相对湿度的精确度达±2％,为了测定煤灰试样的炭化速度,还装置了用磷酸和硫酸铜分解CaCO_3和用碱石棉吸收CO_2的重
We have begun work on this topic on the basis of studying the hydration products of coal ash bricks. In order to study the interaction between CO_2 and the hydration products of coal ash products under different CO 2 concentrations and relative humidity conditions, we produced carbonization equipment that can simultaneously adjust the CO 2 concentration and relative humidity, and adjusted the accuracy of CO 2 concentration to ± 1%. The accuracy of humidity is ±2%. In order to determine the carbonization rate of coal ash samples, a method of decomposing CaCO 3 with phosphoric acid and copper sulfate and absorbing CO 2 with alkali asbestos is also provided.
