Industrial Flyash / Sand AAC Block Plant , Autoclaved Aerated Concreteplant

Flyash/Sand AAC Block Plant/50,000 cbm to 400,000 cbm annual capacity

Brief Introduction of Process

1. First, crush and grind the qualified raw material into powder,

    then measure raw materials for dosage.

    Coal ash (Sand): Lime: Cement: Gypsum: Waste = 60: 18: 12: 3: 6

    Aluminum powder takes 0.075% of total dry material;

    Water and material ratio: 0.6-0.65;

    Note: Concrete parameters shall be adjusted according to practical situation of the raw material.

2. Feed welled measured raw material powder into mixer to make slurry.

3. Through thoroughly mixing, the slurry is poured into mould, ready for casting.

• Adding raw material slurry, waste slurry:          1 minute;
• Adding cement and lime:                       1.5 Minutes;
• Adding aluminum powder suspending liquid:      30- 50 seconds;
• Mixed to even liquid:                           ~3 minutes;
• Casting:                                      1 minute;
• Mixing and casting period:                      ~7 minutes;
• Casting temperature:                           38-42.

4. After pre-curing with a certain temperature & time,

•      the block would reach certain hardness prepare for cutting.
•      Static curing time:                             1.5 - 3h;
•      Static curing chamber temperature:              about ~40;
•      Cutting strength after billets static curing:      &nbs
