ASTM C1777 - 20 Standard Test Method for Rapid Determination

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.

Effect of clay in fine aggregate - Concrete

The Methylene blue test (BS EN 933-9) provides an assessment of the quantity of clay in a sample of rock or aggregate. No limits are given in UK standards as it is not considered sufficiently precise for the purpose of determining harmful fines content, see BS EN 12620 Annex D. The French National Standard has a limit of 1%.
