Fly Ash Testing

Test TypeTest StandardParameterNotes
ChemicalASTM C311 (110°C)Moisture ContentPercentage of moisture in a typical sample
ASTM C311 (750°C)Loss on IgnitionPercentage of material lost during ignition in muffle oven at 750°C
ASTM C114Chemical AnalysisDetermination of Silicon Dioxide, Aluminum Oxide, Iron Oxide, Calcium Oxide, Sulfur Trioxide, Sodium Oxide, and Potassium Oxide
ASTM C311 / C114Available AlkaliCalculates “Equivalent Na2O %” of a typical sample. Equivalent sodium oxide.
ASTM D1426AmmoniaDetermination of ammonia content of a typical sample, expressed on  a mg/kg basis. Method A – Direct Nesslerization. Method B – Selective Ion Electrode.
PhysicalASTM C109Strength-Activity IndexComparison of strength performance of control/test mixtures, using 2″ x 2″ mortar cube specimens
ASTM C151SoundnessStandard autoclave soundness test, performed on samples containing 20% by mass of fly ash/natural pozzolan
ASTM C157Increase of Drying ShrinkageDetermines the impact on drying shrinkage of a supplementary cementitious material, when compared to a control sample
ASTM C185Air-EntrainmentCalculates air content (volume %) of a mortar, utilizing neutralized vinsol resin solution
ASTM C188DensityStandard density (specific gravity) test using volumetric displacement of kerosene
ASTM C430FinenessDetermines the percentage material retained when washed on a 45-µm (No. 325) sieve
ASTM C604DensityAlternate density test for “true specific gravity” of refractory materials by gas-comparison pycnometer
ASTM C1437Water RequirementCompares amount of water required to produce similar consistency material (control vs fly ash/pozzolan)
ReactivityASTM C441 / C227Alkali-Silica Reaction ControlCompares expansion of control/test mortars. Control mortar contains an equivalent alkali of <0.60%. A test cement of higher equivalent alkali is used.
ASTM C1012Sulfate ResistanceMeasures length change of control/test mortars when exposed to a sulfate solution (6 month test minimum)
