QUICKLIME
Quicklime (or Calcium Oxide) is obtained from limestone from selected deposits of white calcium carbonate, with regular crystals having a CaCO3 content of more than 98%. The calcium oxide is obtained by burning the calcium carbonate at a temperature above 1000° C in kilns where the following reaction takes place: CaCO3 + T ° C = CaO + CO2. It is supplied micronized (fineness <90 micron).
Fields of use: “hot lime” mortars for macroporous plasters, lime floors, etc.
The tradition of “hot lime” mortars dates back to ancient times and consists in mixing quicklime, sand and water. Quickime reacts with water to generate heat and, at the same time, binds with sand or other aggregate to form a mortar. This mortar can still be used hot (for some work) or stored for later use. The “hot” mortars have some properties that distinguish them from mortars prepared with lime putty or hydrated lime in powder just because of the effect of the heat generated by the reaction on the aggregates and on any other components of the mixture.
