The effects of removal time of sheathing on strength properties and durability of high-strength concrete with moderate heat portland cement were studied using some full-scale concrete specimens in cold and dry environment. In the experiments, setting time, temperature, compressive strength, length change, carbonation and pore volume of the concrete were measured. From the experiments, the following conclusions were derived: 1. Concrete strength of core specimen was not influenced by removal time of sheathing. 2. Removal time had little effects on carbonation when about 34 hours passed after concrete casting. 3. Removal time had little effects on length change after setting of concrete. 4. Strength propetires and durability of high-strength concrete using moderate heat portland cement are almost equivalent to that of concrete using ordinary portland cement.
