In addition to cement, Secil Group also sells hydraulic lime a widely used binder, particularly in the manufacture of mortars, soil treatment, soil-lime or filler for bituminous products.
Currently we also produce natural hydraulic lime as the result of a research and development process at the Secil Group, which allows for a use compatible with old substrates but with a behavior that meets the rigorous requirements of today.
Hydraulic lime is manufactured by processes similar to those used for the manufacture of common lime.
This material is obtained from the firing of marly limestone, at temperatures between 1000°C and 1500°C.
For this purpose, continuous vertical masonry furnaces with refractory lining are used.
rom this production process calcium oxide, calcium silicates and aluminates are obtained which give the lime its hydraulicity.
