Tap water is taken to carry out full water pre-wetted treatment, processing time 3h to haydite；
(3) raw material mixes
After nano zeolite powder, flyash, albite, Portland cement, river sand are added to full water pre-wetted treatment successively
In haydite, mixing, dry mixing is uniform, and load weighted water-reducing agent, carbon fiber, vanadium carbide then are poured into wherein progress uniform mixing obtains
To mixture；
(4) it foams
Composite foamable agent, cellulose ether, triethanolamine, lauryl sodium sulfate are added in 60 DEG C of water be uniformly mixing to obtain it is mixed
Solution is closed, is subsequently poured into mixture and is uniformly mixed, stirs producing foamed concrete slurry through homogenizer, mixing time is
Slurry cast is entered mould by 2min, and standing demoulds, is put into fog room and conserved to get concrete product afterwards for 24 hours.
