2. Manufacturing
The sole constituent of natural hydraulic lime is a limestone containing 15-20% silica and alumina, as well as a varying percentage of iron.
2.1 Extraction, crushing and screening
Limestone is extracted from underground or open-cast quarries (see figure 2 ). The resulting blocks are crushed in primary crushers, then screened.
