Calcium hydroxide - Wikipedia

Calcium hydroxide (traditionally called slaked lime) is an inorganic compound with the chemical formula Ca 2. It is a colorless crystal or white powder and is produced when quicklime (calcium oxide) is mixed, or slaked with water. It has many names including hydrated lime, caustic lime, builders' lime, slack lime, cal, or pickling lime.

Lime Slaking Equipment - Mineral Processing & Metallurgy

Lime Slaking. If lime slaking efficiency is removed from the economic analysis, the higher cost and reagent consumption of hydrated lime still justifies the installation of a slaker. The proportion of pebble lime to hydrated lime was varied to find the breakeven point between the two slaker systems.

How to Make Cement And Concrete From Scratch

When slacking lime you can use low water amounts and you will be left with a powder or more water and be left with a putty. Either can be used as cement when making concrete. As CO2 in the atmosphere reacts with the cement in your concrete it reverts back to limestone. Basically turns back into stone.

Slaking lime — Materials Technology

Slaking lime. Lime is slaked with water to form calcium hydroxide or hydrated lime (Ca[OH] 2).Lime is used for a variety of purposes, including mortars and plasters in the building industry, in agriculture to lighten and improve soil in various ways, including reducing acidity and in a number of chemical and industrial processes.

What is Quicklime and How is it Made? - ScienceStruck

But the most common treatment is slaking, or addition of water to the quicklime. This is an exothermic reaction, which means it results in the evolution of a large quantity of heat to form calcium hydroxide or slaked lime. The process of hydration is carried out in a continuous hydrator, after which micron-sized slaked lime particles are produced.
