Limestone can be directly processed into stone using crushing equipment and fired into quicklime. Quicklime absorbs moisture or adds water to become hydrated lime. The main component of hydrated lime is calcium hydroxide. The hydrated lime is prepared into lime slurry, lime paste, etc., as coating materials and brick adhesives.

· This type of micro-structure appears to be optimal for further processing by slaking, as there is enough free lime to react with water to disintegrate the burnt lime into a fine powder. The original fineness of the SiO 2 particles is therefore a very important factor, because it also subsequently determines the fineness of the hydraulic components.
