| 概要 |
Concrete's strength increases significantly throughout the curing process, and improper curing may reduce concrete's strength and durability. The development of compressive strength in ordinary Portla...nd cement concrete is examined in this research in association with curing techniques and curing times. Six curing methods, wet rug covering, water curing, immersion in lime water solution (1:25), (1:50) and (1:75) curing and water-based curing compound were utilized. The 28- day compressive strength of the concrete was measured for each curing process and curing period and compared with a relative gain or loss during curing times of 3, 7, 14, and 28 days. Lime immersion curing (1:50) yielded the highest compressive strength after a 3-day curing period. After 7 days of curing, water immersion curing produced the concrete with the maximum strength. Wet rug curing produced the highest strength after 14 days of curing, and finally, lime immersion curing (1:50) again yielded the highest compressive strength when the cubes were cured for the full 28 days. The lime solution (1:50) curing method gives the best results compared to other lime solution curing methods i.e. (1:25) and (1:75). In case of time-constrained for construction, lime solution immersion curing (1:50) and (1:75) can be used for achieving target mean strength but curing should be at least 3 days.続きを見る
