摘要
硅酸钙的加速碳化过程是非水硬性工业固废利用、二氧化碳的捕集与封存以及新型低钙硅酸盐水泥研究的共性关键问题。综述了时间、温度、CO2气体分压及水固比等对碳化速度的影响,统计分析了这些影响因素的最佳范围,并对硅酸钙碳化过程中的化学计量关系、碳化反应及碳化产物的类型进行了总结,提出了硅酸钙类矿物碳化反应模型。
The accelerated carbonation process of calcium silicates is a key issue for effective utilization of non-hydraulic industrial solid waste, CO2 capture and storage, and development of novel low calcium silicate cements. In this review, the effects of carbonation time, temperature, partial pressure of CO2 gas and water-solid ratio on the carbonation rate were summarized, and the optimum range of these factors was analyzed. In addition, a carbonation reaction model of calcium silicate minerals was also proposed.
