An aerated concrete block prepared from cotton hulls is prepared from raw materials in parts by weight as follows: 15-20 parts of cement, 35-40 parts of fly ash, 15-20 parts of the cotton hulls, 6-8 parts of ramie noil fibers, 5-10 parts of quicklime, 0.1-0.3 parts of aluminum powder and 2-4 parts of silicon powder. The aerated concrete block is prepared from the cement, the fly ash and the quicklime which are raw materials of traditional concrete as main raw materials, then the specially treated cotton hulls and ramie noil fibers as well as the silicon powder are added, so that advantages ofstrength, toughness and the like of the block are enhanced by the fibers, the defects of poor dispersion and high probability of agglomeration of the fibers in a cement-based material are overcome, and the prepared aerated concrete block is light in weight, good in thermal insulation and sound insulation properties and high in strength. 种利用棉花壳的加气混凝土砌块，由以下重量份的原料制备而成：水泥15-20份、粉煤灰35-40份、棉花壳15-20份、苎麻落麻纤维6-8份、生石灰5-10份、铝粉0.1-0.
