Utilization of wasted carbon dioxide to cement lining method

在室内试验中，研究了二氧化碳在水泥衬里中的应用，通过水泥的水化作用获得水泥的早期强度。在水泥衬砌条件变化时，水泥的种类；普通硅酸盐水泥、高早硅酸盐水泥、中硅酸盐水泥、硅酸盐高炉矿渣水泥，水灰比：27-60%，空气中二氧化碳浓度；0-10%，混水温度；10 C-20 C，固化时间：1小时-7天，试件制作并进行无侧限抗压强度试验。每种水泥在二氧化碳浓度为40% ~ 60%时均获得了良好的测试结果。通过本研究，我们发现二氧化碳在水泥中的利用是非常有效的。

In the lavolatory experiments, utilization of carbon dioxide to cement lining was studied to get early strength by the hydration of cement.In the change of cement lining condition, kinds of cement ; ordinary portland cement, high early portland cement, moderate portland cement, portland blast-furnace slag cement, water cement ratio : 27-60%, carbon dioxide concentration in the air ; 0-10%, the temperature of mixing water ; 10ﾟC-20ﾟC,curing time : 1hour-7days, the test pieces are made and tested by the unconfined compressive strength. Good test results were obtained at 40%-60% carbon dioxide concentration for each cements.By this research, that were found utilization of carbon dioxide to cement were very effective.
