Abstract

A process for production of natural hydraulic lime comprising at least the operations of selecting raw materials of natural origin, mixing the raw materials in proper proportions, by carrying out a weight dosage which forms compounds having a hydraulic index substantially included between 0,2 and 0,55, reducing into fine grains the mixed raw materials, transforming the fine grains of mixed raw materials into product pieces of mass and sizes so as to allow cooking in a lime kiln, cooking the product pieces at a predefined temperature in order to produce an intermediate product (caustic lime), turning off the intermediate product, seasoning for a predetermined time period the intermediate product in humidity controlled ambient, grinding the intermediate product in order to obtain the natural hydraulic lime.
