The invention discloses a fly ash aerated brick. The fly ash aerated brick comprises the following raw materials in parts by weight: 200-210 parts of fly ash, 5-7 parts of pitchers, 30-45 parts of ordinary portland cement, 1-2 parts of high-boron calcium borate, 30-40 parts of quicklime, 6-10 parts of phosphogypsum, 1-2 parts of lithium carbonate, 2-4 parts of cottonseed hulls, 0.2-0.3 part of aluminium powder, 3-5 parts of expandable graphite, 0.3-0.4 part of hexafluoroacetylacetone, 0.7-1 part of barium metaborate, 2-3 parts of pozzolan and 6-10 parts of a biomass resistance-enhancing agent. The biomass resistance-enhancing agent added into the aerated brick adopts waste resources of barks and cocoa nut husks as biomass raw powder, through enzyme treatment and alkaline treatment, a fiber material with better flexibility is obtained, and is mixed with glycidyl methacrylate for modification to improve the surface resistance, the modified fiber material is mixed with a salt solution, polyvinyl alcohol and the like, and then the mixture is dried, so that not only is the effective resource recycle realized, but also the stability of the biomass resistance-enhancing agent is improved.
