Question: What Is Lime?

What is lime and its uses?

Lime is the versatile mineral. In construction, the dominant use of lime is in soil stabilization for roads, earthen dams, airfields, and building foundations. Lime can be combined with certain additives to produce other metals and is also a key ingredient in mortar and plaster in lime slurry form.

What is lime made of?

Lime is produced through the calcination of limestone (calcium carbonate) in a lime kiln at temperatures at or above 2000 degrees Fahrenheit. The product of calcination of high calcium limestone is “quicklime” or calcium oxide. Quicklime in turn can be reacted with water to produce hydrated lime (calcium hydroxide).

Is lime harmful to humans?

Inhaling lime dust may lead to irritation of breathing passages, coughing and sneezing. If ingested, lime can cause pain, vomiting, bleeding, diarrhea, a drop in blood pressure, collapse, and in prolonged cases, it can cause a perforation of the esophagus or stomach lining.

What is lime used for on dead bodies?

Quicklime is calcium oxide. When it contacts water, as it often does in burial sites, it reacts with the water to make calcium hydroxide, also known as slaked lime. This corrosive material may damage the corpse, but the heat produced from this activity will kill many of the putrefying bacteria and dehydrate the body.
