What is hydrated lime and what is it used for?

Hydrated lime is used to purify waste water and industrial wastes, and control odors. It reduces soil acidity in farms, lawns and gardens. In construction, hydrated lime is an essential ingredient in mortar, plaster, whitewash and stucco. It is also used to stabilize soil for construction projects.

Is hydrated lime a liquid or a gas?

The rocks are then heated to 2500 degrees Fahrenheit in coal or gas fired kilns burning off carbon dioxide and creating calcium oxide. In order for hydrated lime slurry to be produced, the hydrated lime manufacturer adds approximately 20% water to calcium oxide, converting it to calcium hydroxide while avoiding a liquid lime slurry.

What is hydrated white lime?

Hydrated lime, Calcium hydroxide (Ca(OH)2), also called slaked lime, is a white powder produced commercially when quicklime is mixed with water: CaO + H2O → Ca(OH)2. Hydrated Lime has a variety of benefits when used for water and wastewater treatment, including acid neutralization, water softening, and impurity removal ...

What is hydrated lime used for?

In construction, the dominant use of hydrated lime is in soil stabilization for roads, earthen dams, airfields, and building foundations. Hydrated lime can be used to raise the pH of acidic soils. This is also referred to as soil "sweetening."

Is white lime the same as hydrated lime?

The key difference between quicklime and hydrated lime is that the quicklime (or burnt lime) contains calcium oxide whereas the hydrated lime (slaked lime) contains calcium hydroxide. The major source for both quicklime and hydrated lime is the limestone. Therefore, like limestone, these compounds are also alkaline.

What is white lime used for?

Pure lime is pure white and can be used for whitewash, plaster, and mortar.

Can I put hydrated lime on my garden?

Hydrated Lime is designed for use on lawns, gardens, & potted plants. For gardens, work in Hydrated Lime around each plant & water normally. For potted plants, mix one tablespoon of Hydrated Lime in one gallon of water & apply as you would normally water.

How do you use hydrated lime for soil?

Apply 3.5 pounds of hydrated lime to every 70 square feet of garden to raise the pH level one point. Work the lime into the soil by hand, with hand tools or a tiller, then water as usual. Hydrated lime should not be mixed with fertilizers or other garden chemicals.

What happens when you mix hydrated lime with water?

Lime reacts readily with water to produce slaked lime, which is the chemical compound calcium hydroxide. A considerable amount of heat energy is released during this reaction.

What is the difference between agricultural lime and hydrated lime?

Slaked lime (also called hydrated lime or builder's lime) is calcium hydroxide (Ca(OH)2) and has a higher neutralising value than agricultural lime but is more expensive and not usually applied to pastures.

What's the difference between hydraulic lime and hydrated lime?

Hydraulic limes (so called because they set under water) are made in the same way as non-hydraulic lime but using different limestone. They are sold as hydrated lime and have an initial set when water is added, followed by hardening while they absorb carbon dioxide.

Is hydrated lime harmful to humans?

Hydrated lime is strongly alkaline and can cause severe injury. Contact with eyes or skin can cause irritation and possible irreversible tissue damage, corrosion damage, chemical burning and corneal damage. Wear eye protection, gloves, long-sleeved shirts and pants to prevent skin contact.

Can hydrated lime be used as paint?

If you'd like to forgo pre-making the lime putty mix, you can still use straight hydrated lime powder in it's place and produce fairly similar limewash paint results.

Is lime better than cement?

Physical Properties Lime hardens much more slowly than cement-containing mortars, making it much more workable. Lime is also less brittle and less prone to cracking, and any cracked areas can absorb carbon dioxide and mend over time.

Standard Hydrated Lime

Hydrated lime products are typically used in chemical manufacturing, water and waste water treatment, acid neutralization and other environmental applications.

Activated Hydrated Lime

Mississippi Lime Activated Hydrated Lime “AHL” offers very low grit attributes, dosage reduction over Standard Hydrated Lime, less variability and faster reacting speed. Operational savings opportunities for water treatment applications.

Hydrated Lime FGT

This high purity hydrated lime is the industry leader for DSI for SO3 mitigation. Mississippi Lime Flue Gas Treatment grade assures the customer of a reactive product (>21 m2/g BET surface area) that is proven in the toughest full-scale applications.

High Reactivity Hydrated Lime

The second generation product for DSI. This material is tailor-made for applications where high reactivity and performance are required.

Liquid Calcium Hydroxide

Liquid Calcium Hydroxide (LCH) is used in water treatment, waste water treatment, acid neutralization and as a substitute in many “liquid caustic” applications. Dust free, LCH can be the solution to many alkali handling problems.

Product Overview

The TXI Hydrated Lime 50 lb. is useful to substantially increase the stability, impermeability and load-bearing capacity of subgrade. The lime is able to reduce plasticity and moisture-holding capacity. The lime is also designed to improve stability and raise the pH level in soil.
