CONCRETE, CONCRETE STRUCTURE AND MANUFACTURING METHOD OF CONCRETE
PROBLEM TO BE SOLVED: To provide a concrete capable of having efficient quality even when using a coal ash molten slag as a part of a fine aggregate for concrete, a concrete structure and a manufacturing method of the concrete.SOLUTION: There is provided a concrete containing cement, a fine aggregate and an admixture, where coal ash molten slag and an ordinary aggregate (land sand) less in fineness modulus and larger in water absorptive than the coal ash molten slag and occupying 50% or more in the fine aggregate by volume ratio and a thickener (one of a thickener one pack type high performance AE water-reducing agent (V), limestone fine power (LS) and cellulose type thickener (V2)) is used as at least a part of the admixture.SELECTED DRAWING: Figure 2
【課題】石炭灰溶融スラグをコンクリート用細骨材の一部として使用しても、十分な品質を得ることができるコンクリート、コンクリート構造物及びコンクリートの製造方法を提供する。【解決手段】セメント、細骨材及び混和材料を含有するコンクリートであって、細骨材として、石炭灰溶融スラグと、石炭灰溶融スラグよりも粗粒率が小さく且つ吸水率が大きい、細骨材中の体積比で５０％以上を占める普通骨材（陸砂）とが少なくとも使用され、混和材料の少なくとも一部として、増粘剤（増粘剤一液タイプの高性能ＡＥ減水剤（Ｖ）、石灰石微粉末（ＬＳ）、セルロース系増粘剤（Ｖ２）のいずれか）が使用されている。【選択図】図２
