RELATIVE STRENGTH OF METAKAOLIN CONCRETE CURED AT NORMAL AND LOW TEMPERATURES

摘要：

The performance of concrete containing metakaolin (MK), subjected to low and normal temperature curing is investigated. Cement was partially replaced (by mass) with 0％, 5％, 10％, 15％, 20％ and 30％ MK. The water to binder ratio was maintained at 0.5 for all mixes. Concretes were subjected to water curing at 5℃ and comparison was made with MK concrete cured at 20℃ in a previous investigation. The results show that the relative strength to 28 days is lower for concrete subjected to low curing temperature compared with curing at 20℃ whereas after 28 days the trend was exactly the opposite. A suggested explanation for this behaviour is presented.
