ASTM C1777, Methylene Blue Value. C1777 provides a rapid test for laboratory and field use to determine the amount of methylene blue adsorbed by a specimen of fine aggregate or mineral filter. The test in ASTM C1777 will be used to distinguish between harmful and non harmful fines in concrete aggregate, says Eric Koehler, vice president

Relationship between methylene blue values of concrete

The fine granular structure and surface activity of clay minerals increase the amount of mixing water needed to provide workability in concrete. Even when the microfine material percentage in fine aggregate is low, the methylene blue value of the fine aggregate increases when materials of clay origin are present. In this study, methylene blue values were determined in fine aggregate

2002 10 8   The purpose of this study was to investigate the relationship between methylene blue value, initial soil suction and the swell percentage of expansive soil samples. In this study, commercially processed kaolinite and bentonite mineral clays were mixed in preselected proportions to obtain soil samples possessing a wide range of plasticities and different swell
