Evaluation on The Compressive Strength of Concrete Incorporating High Volume Blast-Furnace Slag Subjected to Initial Frost Damage

摘要：

　　Construction works that uses concrete incorporating a high volume of blast-furnace slag (BFS) during the winter season increases the risk of being subjected to initial frost damage as it noticeably delays setting and hardening.Assuming that the concrete incorporating a high volume of BFS was affected by freezing at an early age during the winter conditions,this study is to investigate the effect of strength degradation by early freezing and curing methods on compressive strength.As a result,freezing at early age highly degraded the compressive strength regardless of the types of concrete.After influenced by initial frost damage,water curing at 5℃ improved the long-term strength and water curing at 30℃ enhanced the long-term strength as well as the early strength.
