The white blocks industry dates back to 1929, when the Swedish city of Axoholt witnessed the first production of Cellular concreteproducts.
Components of white blocks
Mixing sand granules mixed with lime, cement, water and aluminum powder. Aluminum powder is a fuel. Hydrogen gas makes a bloating of the mixture with small sporadic air bubbles evenly.
After this phace, the semi-rigid mixture is entered into a specially designed evaporator to evaporate the water vapor at 200 ° C. After drying, the hot air is only present in the pores. No air, water or any contaminants enter at this stage.
1-White blocks insulation reduce the energy needed for heating or cooling
2-The density of the insulating white blocks is 500 kg / m3. The weight of the insulating white blocks is less than one third of the weight of the regular cement blocks.
3-The White blocks insulation in the Shamlan factories are made of organic materials against fire and flammability.
4-The white insulation blocks have high insulation ability, isolating 42 dB of sound for a 20 cm wall.
5-You can cut the White blocks insulation with the simplest manual tools such as hand saw or electrolyte finely.ز against fire and flammability,
