| Research Abstract |
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.
