Quicklime


High Calcium Quicklime Powder  used for making Hot-lime mortars and Lime Putty

Description


Quicklime is limestone (a rock rich in calcium carbonate) that has undergone a chemical change in a kiln, liberating it of all the carbon and water it holds, creating a very unstable material (calcium oxide) which needs to hydrate. Quicklime will do so very energetically with any moisture it comes into contact with, resulting in a strong exothermic reaction and the production of lime. The addition of water, slaking, has the potential to produce temperatures exceeding 250C very quickly. However, when creating a mortar the quicklime can reach these high temperatures as hot spots only, and the overall temperature of the mortar should not exceed 100C – the temperature at which the water turns to steam.
;

Finely powdered Calbux 90 is used by ourselves to manufacture Hot Lime mortars.  When blended with good quality sands in a pan mixer, it produces a lime rich and very fatty workable mortar for re-pointing and rebuilding solid walls.   A hot-lime mortar is an excellent and very vapour permeable mortar, with a good ‘sticky’ consistency and high-water retention. 



Quicklime (Calcium Oxide) is a highly reactive and quite dangerous material, please make sure you understand the risks and have taken suitable safety precautions before ordering. This material must be stored in a cool dry environment away from direct sunlight.
GREAT CARE & FULL PPE IS NECESSARY WHEN USING THIS PRODUCT PLEASE SEE SAFETY SHEET
