Alkali, or Alkaline, soils are clay soils with high pH (> ), a poor soil structure and a low infiltration capacity. Often they have a hard calcareous layer at to 1 metre depth. Alkali soils owe their unfavorable physicochemical properties mainly to the dominating presence of sodium carbonate, which causes the soil to swell and difficult to clarify/settle.
Gypsum, unlike cement, is a physical structure rather than a chemical structure. The needlelike gypsum crystals form a network to give the board its physical integrity The crystals are closely interwoven, giving the core most of its wet strength. After drying, the frictional forces of these crystals increase the strength of the core.
