What are the uses and characteristics of aerated brick waste: the generation of aerated block waste is mainly caused by transportation, secondary handling, technological cutting, etc. Aerated brick waste can be reused to produce autoclaved bricks after powdering The activity of powder A8 is the highest, reaching about 70%. The powder replaces 30% cement and is mixed into autoclaved bricks. The compressive strength reaches 1.6 MPa, which is slightly lower than that of the reference sample, and the frost resistance is good. Microscopic analysis shows that there are a large amount of hydration products such as tobermolite and calcite inside the autoclaved brick mixed with 30% waste aerated brick powder. The interaction between the activated powder and cement is significant, which makes the internal structure of the autoclaved brick more compact and improves the compressive strength of the autoclaved brick.
The technological process of producing autoclaved bricks from waste aerated bricks: the waste aerated bricks are crushed and then crushed with a waste brick crusher for secondary crushing, followed by mixing, digestion, secondary mixing, brick pressing, static stop, and steam curing And other processes to make autoclaved bricks.
