Production of silicon-limestone bricks

They are obtained with 10% quicklime and 90% silicon-rich sand. They are moistened by pressing lime with sand and water. Hardening takes place with steam under pressure in autoclaves and finally they are cooled in air, producing their carbonation.

In silica-limestone bricks, the use of lime activates the pozzolanic reaction with silica sand and clay, producing bricks with high mechanical and thermal performance.
