　　ASTM C1777-2015

　　中文名称：用色度计快速测定细集料或矿物填料亚甲兰值的试验方法

　　英文名称：Standard Test Method for Rapid Determination of the Methylene Blue Value for Fine Aggregate or Mineral Filler Using a Colorimeter

　　原文名称：Standard Test Method for Rapid Determination of the Methylene Blue Value for Fine Aggregate or Mineral Filler Using a Colorimeter

　　范 围：This test method is used to determine rapidly the amount of methylene blue adsorbed by a specimen of fine aggregate or mineral filler. The result is reported as a methylene blue value in units of mg of methylene blue adsorbed per g of fine aggregate or mineral filler. The methylene blue value is a function of the amount and characteristics of clay minerals present in the test specimen. High methylene blue values indicate increased potential for diminished fine aggregate or mineral filler performance in a cementitious mixture due to the presence of clays.
