文摘
A new experimental method of accelerated leaching is developed for the corrosion evaluation of cement-mortar lining under a flowing solution. The accelerating factor of 6M NH4Cl solution is 40, so the relation of accelerated and conventional leaching of lining is obtained. The addition of 40% slag to lining can improve its microstructure, slow down its leaching process, and enhance its leaching resistance.
