Fly Ash Testing
| Test Type | Test Standard | Parameter | Notes |
|---|---|---|---|
| Chemical | ASTM C311 (110°C) | Moisture Content | Percentage of moisture in a typical sample |
| ASTM C311 (750°C) | Loss on Ignition | Percentage of material lost during ignition in muffle oven at 750°C | |
| ASTM C114 | Chemical Analysis | Determination of Silicon Dioxide, Aluminum Oxide, Iron Oxide, Calcium Oxide, Sulfur Trioxide, Sodium Oxide, and Potassium Oxide | |
| ASTM C311 / C114 | Available Alkali | Calculates “Equivalent Na2O %” of a typical sample. Equivalent sodium oxide. | |
| ASTM D1426 | Ammonia | Determination of ammonia content of a typical sample, expressed on a mg/kg basis. Method A – Direct Nesslerization. Method B – Selective Ion Electrode. | |
| Physical | ASTM C109 | Strength-Activity Index | Comparison of strength performance of control/test mixtures, using 2″ x 2″ mortar cube specimens |
| ASTM C151 | Soundness | Standard autoclave soundness test, performed on samples containing 20% by mass of fly ash/natural pozzolan | |
| ASTM C157 | Increase of Drying Shrinkage | Determines the impact on drying shrinkage of a supplementary cementitious material, when compared to a control sample | |
| ASTM C185 | Air-Entrainment | Calculates air content (volume %) of a mortar, utilizing neutralized vinsol resin solution | |
