Calcium silicate board 20х600х1200 mm

View by manufacturing method

First, slaked lime and silica (quartz sand, mineral slag, or sawdust with silica) are carefully crushed and sieved. The raw materials are then mixed with water to form a paste, and special binders and fillers are added. The mixture is formed into slabs of the required size by pressing or casting. The slabs are placed in an autoclave, where they are treated with steam under high pressure and temperature (approximately 180–200°C). This converts the lime into durable calcium silicate crystals, imparting fire resistance and high mechanical strength to the slabs. After the autoclave, the slabs are cooled, dried, and, if necessary, sanded to achieve a smooth surface.

Chemical composition

The main components are calcium oxide (CaO) – approximately 60–70%, silicon dioxide (SiO₂) – approximately 25–35%, and water (H₂O). Minor components include aluminum, magnesium, and iron. Fillers and stabilizers (e.g., cement, ash, and gypsum) are sometimes added.

Type by purpose

Calcium silicate boards are used for partitions, wall cladding, ceilings, and floors where thermal insulation and fire protection are required. They are also used in boiler rooms, furnaces, fireplaces, chimneys, and high-temperature process units. They are also used as a fire-resistant and thermally insulating material for air ducts. They are also used for thermal insulation of pipes and equipment, especially for pipelines carrying hot media and tanks. They are also used to enhance the fire resistance of structures and to insulate walls and ceilings.
