| Technology description including background system | Expanded clay is an additive which requires specially suited clays with uniform and finely distributed organic components for its production. The clay from the open cast mine is formed into shots and burned in a drum type furnace system at 1.200°C. The addition of iron oxide or bleaching earth can support the swelling process by means of oxygen splitting by up to 7%. The organic constituents in the clay are burned off and the shots swell. The expanded clay can be produced at apparent densities of approx. 300 to 800 kg/m, according to its required use. Expanded clay grains and sand are used for bricks, wall units, light plaster, light concrete and as bulk solids in construction and green areas. |
