• In order to assure the quality of concrete structure in construction process, the odor strength measured by odor sensor was used to evaluate curing effect. Then, the compressive strength, temperature and humidity and odor strength in ordinary concrete N and portland blast-furnace slag cement concrete BB were shown in water curing (standard curing), indoor and outdoor atmospheric curing condition. The odor strength in the concrete N and BB was related to the change in the temperature and humidity which greatly influenced on the curing effect. The difference between odor strength in the standard curing and that in each curing condition was defined as the difference in the odor strength. And the difference in odor strength in slag powder concrete BP cured in water curing (standard curing) for different period before exposing in outdoor atmosphere in winter season were evaluated at the age of 14 days. A necessity to prolong the moisture curing for the slag powder concrete BP compared with the ordinary concrete N to obtain a required curing effect was shown by measuring the odor strength and long term compressive strength.
