Acid Sulphate Soils Testing Naturally occurring, acid sulphate soils and sediments contain iron sulphides, most commonly "pyrite," which can rapidly form sulphuric acid when exposed to oxygen. This acid can leach into surrounding environments, possibly causing damage to infrastructure, and leaching iron and aluminium and other heavy metals into ...

Corrosive Soils. Causes, Effects and Mitigation. By Hossein Arbabi. TESTING ENGINEERS, INC. Soils, like any environment, can be corrosive. If we only used soil to plant flowers and trees, we probably wouldn't care too much – but as it stands, the dirt beneath our feet supports man-made structures of all kinds, and much of our utilities infrastructure is buried in it.

THRESHOLD SULFATE LEVELS IN SOILS The current methodology to identify risk of sulfate-induced damage is based on the concentration of available (usually water soluble) sulfates in the soil. Sulfate contents are generally expressed either in ppm (parts per million) or mg/kg (which is equal to ppm) or in a percent dry weight of soil (10,000 ppm ...

Acid sulfate soils are naturally occurring soils, sediments or organic substrates (e.g. peat) that are formed under waterlogged conditions.These soils contain iron sulfide minerals (predominantly as the mineral pyrite) or their oxidation products. In an undisturbed state below the water table, acid sulfate soils are benign. However, if the soils …

A new test, the Soxhlet method (ACI 222.1), has been de-veloped to test these aggregates or to test concrete made with these aggregates. This test uses chunks of concrete or aggregate instead of crushed and powdered material. The chunks or pieces are treated with boiling water, which is then tested for chloride content. So far, the test …
