Abstract: The compressive strength, chloride penetration resistance and microstructure of two high-performance concretes were examined under three curing conditions. Curing conditions include standard curing (SC), matched curing (MC, which means sealed concrete specimens curing at temperature controlled box) and matched curing of naked concrete (NMC) according to development law of temperature measured in mass concrete on site. Results indicate that concrete under MC and NMC show higher resistance to chloride penetration than the one under SC. Concrete under MC has a little bit lower chloride penetration than those under NMC, but the compressive strength of specimens under NMC was higher than the one under MC at 56d. In addition, concrete under NMC and MC have higher early strength than under SC,especially at early age. However, the order of curing conditions affecting compressive strength of concrete at 248 days is: SC>NMC>MC.
