초록

The increase of activated carbon contents in fly ashes accelerate the corrosion of steel embedded in ordinary portland cement(OPC) mortar. Cement losses its identity of colour when the % of carbon is increased. More than 60[%] area was rusted when carbon content is increased beyond 8[%] for the exposure period of one year. Comparable corrosion rate with OPC was obtained up to 6[%] carbon level only. The tolerable limit of replacement for various admixed carbon system under aggressive alternate wetting and drying condition with 3[%] NaCl was found to be 6 to 8[%].
