High strength lightweight concrete composition including artificial lightweight aggregates

摘要

The present invention relates to a high strength lightweight concrete composition including water, cement, fine powder of blast furnace slag, and artificial lightweight aggregate, wherein the artificial lightweight aggregate is pre-wetted and a mixing ratio is adjusted. According to the present invention, the high strength lightweight concrete composition is capable of solving the problem occurring due to a high water absorption rate of artificial lightweight aggregate when applied to concrete and meeting criteria according to the concrete standard specification.
