cement process photos in limestone

Limestone is used due to its high content of calcium oxide, which is the main component of cement and usually makes up around 65 percent of the final product. The amount of clay used depends on its content of silicon oxide, which makes up approximately 20 percent of cement powder.

Mar 04, 2013· Calcium Carbonate is the most natural and common form of lime and the one that other forms of lime will naturally turn into if exposed to the environment. Quicklime: If we take our Limestone rocks or shells and heat them up to a red heat, we drive off the carbon completely replacing those three carbon atoms with one oxygen atom to make CaO (calcium oxide) one calcium to one Oxygen.

Calcium oxide: quicklime

If the raw material consists of limestone with clay (SO 3, and minerals), creates hydraulic lime. The clay is converted to calcium aluminates and silicates during the burning process .This makes an air hardening lime share and a waterreactive hydraulic component that in a chemical reaction becomes hard, different from just drying out in air.

The limestone must be of suitable chemical composition to produce quicklime not all limestone will do. The limestone is crushed to the proper size and then heated in vertical or rotary kilns to 1700°2450°F. This heating process, called "calcination," converts the limestone into quicklime and carbon dioxide.

MAKING AND USING LIME MORTARS

Lime is derived from limestone or Calcium Carbonate (CaCO3), which has been burnt in a lime kiln at over 800 degrees centigrade to produce quicklime or Calcium Oxide (CaO). In this process carbon dioxide and any water is driven off. Quicklime is potentially dangerous having an avid thirst for water.

The Limestone Chemistry Cycle Activity

Calcium carbonate (limestone) is turned into calcium oxide (quick lime) by heating. This dissolves to form calcium hydroxide (slaked lime) which can be used to test for carbon dioxide if it is dissolved in water to make limewater.

Lime Production from Limestone Current Technology

Limestone is a source of calcium carbonate and is heated to convert the calcium carbonate into calcium oxide. This process is generally carried out in large rotary kilns or vertical shaft kilns where high temperature is required. Quicklime is produced in the calcination process, which can be crushed depending on it's use.

Heat transfer in lime burning can be divided into three stages: a) Preheating zone. Limestone is heated from ambient to above 800 °C by direct contact with the gases leaving the calcining zone ( products of combustion, excess air and CO 2 from calcination). b) Calcining zone.

Answer Wiki. In a killan (Furnace) Limestone's are transformed into Quick Lime (CaO), which is kind of white in color and soft than stone. If you add water to quick lime what you get is slaked lime and the process is called slaking. If you add just enough water to consume all quicklime, it is called Dry slaking.

Most commercial producers use the recarbonisation method of PCC production where limestone is converted into calcium oxide (lime) and carbon dioxide by calcination at high temperatures. After calcination the lime is slaked with water and the resulting milk of lime is purified and recarbonised with the carbon dioxide obtained directly from the calcination process.
