The invention relates to a process and an installation for obtaining cellular concrete and cellular concrete thus obtained that may be used in masonry and thermal and sound insulation works, that may be placed directly or cast into moulds. According to the invention, the process is characterized in that, in the mixing chamber there takes place the introducing of the dry solid components of the mixture, while rotating in the mixing chamber there is introduced air, followed by introducing a mixture of water and additives comprising the gas entrainer and the organic binders, and continuing the rotation then in a discharge chamber there taking place the introducing of the air, equal as a value with the pressure in the mixing chamber, then putting the mixing chamber in communication with the discharging chamber, finally there taking place the gravitational discharging into the mould and equalizing the pressure in the discharge chamber and the pressure in the mixing chamber with the atmospheric pressure, and after the expansion, the mixture mass is discharged from the discharging chamber wherein the expansion took place, and it is let to rest for 5 - 10 hours at the atmospheric pressure followed by the said cutting and palletizing operations. |
