Gypsum Induced Strength Behaviour of Fly Ash-Lime Stabilized Expansive Soil
Physical and engineering properties of soil are improved with various binders and binder combinations. Fly ash and lime are commonly used to improve the properties of expansive soils.

calcitic limestone deposits. The main use of lime is to raise soil pH (to reduce acidity). In the same manner that CaCO 3 neutralizes sulfuric acid in the equation above, it also neutralizes acidity in low pH soils. Unlike gypsum and calcium sulfate anhydrite, lime solubility is dependent on soil pH. Its solubility increases in acid
Managing Salt-affected Soils for Crop Production
Sodic soils require the addition of soluble calcium, followed by leaching of sodium. Calcium promotes soil aggregation. Gypsum is the most common material used to supply calcium for sodic soil reclamation. Elemental S is useful for sodic soil reclamation only when the soil contains free lime. Saline-sodic soils must be treated for sodicity first.

In soils containing calcium carbonate, alternatives to gypsum can be effective. Mineral lime (calcium carbonate) in these soils can be converted to gypsum by adding sulfur, sulfuric acid, or other acidic or acid-forming materials (see Table 1 for equivalent quan-tities of various soil amendments). The acid dissolves the calcium
