Lime Kiln Dust

Lime Kiln Dust will react with water, chemically absorbing water and, at the same time, producing heat which can cause evaporation. This allows the moisture content in wet and unworkable soils to be adjusted to a more optimum value. One common application would be a building site during a wet, rainy season. Absorption of free water can result ...
