Manufactured from the same components as conventional concrete: cement, sand and water in addition to aluminum powder and other additives
Siporex is produced by a highly complex and advanced manufacturing process in our factory under the careful control of chemists and engineers. Siporex is made either as steel reinforced panels using moulds 6 meters long, 1.5 meters wide and 600 mm deep or as non-reinforced blocks using moulds 6 meters long, 1.5 (or 1.2) meters wide and 600 mm deep.
Weight: Siporex products are supplied with nominal dry density of 550 kg per cubic meter which is less than a quarter of that of conventional concrete. Other densities such as 450 per cubic meter or less can also be produced upon request. Due to its light weight, the number of trailers required to transport Siporex materials is much less than those required to transport conventional precast panels and handling at site can be carried out with ease.
Compressive Strength: Siporex is solid and has a high compressive strength in relation to its weight, which in the aspect of application is very sufficient to take building loads. Siporex achieves its strength during the autoclaving process. The minimum strength of Siporex material is 35kg/cm2 for nominal dry density of 550 kg/m3:
Thermal Conductivity: The thermal conductivity (“k” value) for completely dry Siporex of density 550kg/m3 is 0.144 W/mºC. The air bubbles trapped in Siporex are giving10 times better insulation properties compared with conventional dense concrete. This is reflected in considerable savings of electricity consumption and improved indoor comfort.
