Embodiment 1
[0018] Embodiment one: the formula of foamed concrete of the present invention comprises external admixture, cementitious material and chemical auxiliary agent, and every kilogram of foamed concrete comprises the external admixture that mass percentage is 25%, mass percentage is the cementitious material of 45%, and The mass percentage is 15% chemical auxiliary agent, the cement clinker, calcium oxide and bone glue, and the mass ratio of the three components in the cement material is 2:2:1. The external admixture includes industrial waste, and the industrial waste includes one or a mixture of fly ash, wet ash or coal gangue after spontaneous combustion. The external admixture can also include aeolian sand, sand, fly ash, and coal gangue after spontaneous combustion in any proportion. Industrial waste is used as an external admixture to realize waste recycling. Adding aeolian sand and sand is mainly It is to fill the external admixture.

Embodiment 2
[0025] Embodiment two: the formula of foamed concrete of the present invention comprises external admixture, cementitious material and chemical auxiliary agent, and every kilogram of foamed concrete comprises the external admixture that mass percentage is 40%, mass percentage is the cementitious material of 50%, and The mass percentage is 5% chemical auxiliary agent, the cement clinker, calcium oxide and bone glue, and the mass ratio of the three components in the cement material is 2:2:1. The external admixture includes industrial waste, and the industrial waste includes one or a mixture of fly ash, wet ash or coal gangue after spontaneous combustion. The external admixture can also include loam, which can be mixed with fly ash and coal gangue after spontaneous combustion in any proportion. Industrial waste is used as the external admixture to realize waste recycling. The main purpose of adding loam is to fill the external admixture .
