General Description

The Methylene Blue Test of fine aggregate is a measure of the amount of potentially harmful fine material present such as clay and organic material. Material passing the No. 200 (75μm) sieve is maintained in dispersion with distilled water by mixing with the Magnetic Stirring Hot Plate. Methylene Blue solution is titrated into the stirred dispersion in increments until a drop of the mixture on fi lter paper shows a blue ring indicating that the sample can absorb no more reagent. The MBV is simply a measure of the amount of reagent absorbed and is proportional to the amount of clay or organic material present. Methylene Blue Reagent solution is light sensitive. The solution shelf life is 4-6 months maximum, when stored in a dark cabinet in foil-wrapped amber bottles.
