Limestone is burnt to calcium oxide (quicklime) and in a second step water is added to create hydrated lime. meister mills can be used for grinding natural limestone as well as burnt lime to the desired particle size. Hydrated lime reacts with carbon dioxide to create calcium carbonate.

A limepit is either a place where limestone is quarried, or a man-made pit used to burn lime stones in the same way that modern-day kilns and furnaces constructed of brick are now used above ground for the calcination of limestone (calcium carbonate) and by which quicklime (calcium oxide) is produced, an essential component in waterproofing and in wall plastering (plaster skim).

Limestone dissolves at an average rate of about one-twentieth of a centimeter every 100 years. What happens when you mix vinegar and lime water?

Lime burn, as a rule, is obtained, neglecting safety, in the process of its extinguishing. Quicklime, which is a calcium oxide, is a highly toxic caustic substance. Slaked - is a strong base and chemically reacts with other substances like alkali, but when water enters it, a violent exothermic reaction no longer occurs.

Slaked lime is mainly used in building because it is fat, i.e., it makes workable mortar and rendering and plaster mixes. A lime mortar becomes stiff initially by evaporation or loss of water to absorptive materials such as bricks, but subsequent hardening depends on the chemical reaction with carbon dioxide from the air (carbonation) reforming the original calcium carbonate (limestone).

Nature has built up a rich reservoir of lime-containing stone over millions of years. The calcium-carrying sediments contain limestone with a calcium carbonate (CaCO 3) content of more than 98 % - a purity unreached anywhere else in Switzerland.Using this unique raw material, we at KFN produce a wide range of lime and gravel products for an ample spectrum of industrial uses, taking advantage ...
