Hydrated Lime
(Calcium Hydroxide)

When your process calls for a fine, free-flowing lime that disperses evenly and delivers high available calcium hydroxide, hydrated lime is the product to specify. Hydrated lime, chemically known as calcium hydroxide, is produced by introducing water to calcium oxide in a controlled environment. It has small particle size, good flow properties, high surface area, and high total and available calcium hydroxide.

Pete Lien & Sons produces hydrated lime from high-calcium limestone and supplies it from Rapid City, South Dakota, Frannie, Wyoming and Laramie, Wyoming, with truck or rail delivery across North America. We provide a wide range of options, from the highest quality available on the market to a low cost alternative.

What Hydrated Lime Is Used For

Asphalt paving additive. Hydrated lime is a proven anti-strip additive that improves the bond between asphalt binder and aggregate, extending pavement life.

Water and wastewater treatment. Treatment plants use hydrated lime for pH adjustment, softening, and precipitation of impurities.

Soil amendment. Hydrated lime conditions and stabilizes soils for construction and corrects soil acidity in agricultural settings.

pH neutralization. Its fine particle size and high reactivity make hydrated lime an efficient neutralizing agent for acidic streams and byproducts.

Food grade calcium additive. For food and beverage processes, we produce NutriLien HQ, our dedicated food grade hydrated lime. See the Food Grade Lime (NutriLien HQ) page.

FREQUENTLY ASKED
QUESTIONS

Hydrated lime is calcium hydroxide (Ca(OH)2), a fine dry powder produced by reacting quicklime (calcium oxide) with water in a controlled process called slaking. It is widely used for pH control, water treatment, asphalt, and soil applications.

No. Quicklime is calcium oxide; hydrated lime is calcium hydroxide. Hydrated lime is less concentrated but safer and easier to handle, store, and feed. If your process needs the higher reactivity of calcium oxide, see our Quicklime page.

Yes. We offer 50 lb and 35 lb bags in addition to 1 ton supersacks and bulk trailers, available from our Rapid City, SD location.
