High Quality AAC block machine - ZN

AAC Block Introduction

Autoclaved aerated concrete block (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.

We can supply the entire solution of the AAC plant, Capacity from 50,000m3-350,000m3/ year.

We have rich experience to built AAC plant. And welcome you visit our factory!

Process chart
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 45mintues, the high closed cellulated AAC unit is cut to size and formed by steam-curing in a pressurized chamber (an autoclave) for 10 to 12 hours. The result is a non-organic, non-toxic, airtight material that can be used for wall, floor, and roof panels, blocks.
