摘要 |
<p>PURPOSE: Provided are a granulated slag having unit weight of 1.45-1.70 g/l, which is used as a substitute to sand for concrete, and a concrete composition comprising the granulation slag. CONSTITUTION: The slag, which is used as a substitute to sand for concrete, has unit weight of 1.45-1.70 g/l. The concrete composition excellent in durability, comprises the slag having unit weight of 1.45-1.70 g/l so as to replace 30 wt% or less of the sand with the slag having unit weight of 1.45-1.7 g/l. The concrete composition comprising 50% or less of the slag as sand is effective to produce a concrete construction requiring durability.</p> |
