Description
Autoclaved aerated concrete brick machine
AAC Block Production Line
AAC is made from silicon material (silica sand, or recycled fly ash
and silica gangue) and calcium material (lime, cement), mixing with
foaming additive (aluminum powder), batching with water, the
reaction between aluminum and concrete causes microscopic hydrogen
bubbles to form, expanding the concrete to about five times its
original volume. It is made into the multi-cells silicate products
by the processes of resting, tilting, cutting and autoclaving.
Process chart of AAC block production line
To manufacture AAC, cement is mixed with lime, silica sand, or
recycled fly ash, water, and aluminum powder or paste. The slurry
is poured into moulds where a chemical reaction occurs, the
reaction between aluminum and concrete causes microscopic hydrogen
bubbles to form, expanding the concrete to about five times its
original volume. After evaporation of the hydrogen in the mold for
*5mintues, the high closed cellulated AAC unit is cut to size and
formed by steam-curing in a pressurized chamber (an autoclave) for
*0 to *2 hours. The result is a non-organic, non-toxic, airtight
material that can be used for wall, floor, and roof panels,
blocks.
Project cases
With abundant air cells and micro apertures inside the aerated
brick, it has good performance of heat insulation and preservation.
In addition, the most prominent advantage is its plasticity. Due to
the lightness and the lower hardness, AAC units are available in
numerous shapes and sizes according to the real construction usages
and customer's requirements.
