AAC block Manufacturing Process

The Aerated Autoclave concrete consists of mainly two process- Aeration and Autoclaving

The aeration process is due to reaction between quick lime and aluminum powder. In aeration process lime reacts with aluminum powder to produce Tricalcium Hydrate and Hydrogen. This leads to rising of the cake and makes the blocks truly lighter.

Autoclaving is the process of producing high pressure and high temperature steam curing in close vessels. Autoclave is a long vessel with a temperature of about 185 degree and pressure at about 700 Kpa. AAC blocks undergo autoclaving for about 14 to 18 hours. This provides required strength to the blocks.

Quality is of paramount importance, as we intend to provide our customers/end-users, finest product of highest standard of quality & strength. For this end in view, rigorous Lab tests of all input material – whether it is Cement, Lime, aluminum powder or gypsum or other essential additives- are conducted prior to application in AAC block production process.  Then, at every stage of production, random tests are undertaken at regular interval during the batch process. Thereafter, the final product is subjected to required physical & chemical Tests including the Compressive Strength Test of random samples drawn from each batch.
