At first of the job, it was considered that the Recommendations obtainable online for making Aircrete ended up strong.

Whilst Aircrete incorporates a big level of foam, that may be disposed of simply, heightened precaution nonetheless really should be taken when cleaning any excessive material.
The dry ingredients like cement, sand, sand + fly ash or fly ash alone shall be fed into the mixer first and thoroughly blended to be certain even distribution of cement. The right volume of water shall be additional thereafter continuing the mixing. The preformed foam, that is produced by Mixing the foam concentrate, water and compressed air in predetermine proportion in a foam generator, calibrated for a selected discharge amount, shall be additional in calculated total on the slurry of cement, sand, fly ash and water inside the batch mixer.
