摘　　要：通过实验室模拟试验,研究了生石灰、铝粉膏及水的用量对利用固硫灰渣生产蒸压加气混凝土砌块的干密度及抗压强度的影响。试验结果表明:当固硫灰渣的用量较大时,生石灰的用量是主要的影响因素,其用量不应低于17%;铝粉膏的用量对抗压强度的降低影响较显著,对干密度的减少影响相对较小,其用量不宜超过0.08%;在满足砌块生产时对料浆稠度要求的条件下,水的用量主要影响抗压强度。The influences of quicklime, aluminite pastes and water in different contents on the dry density and compressive strength of autoclaved aerated blocks which are mainly made of fluidized bed combustion ashes （FBCA） are studied by experimental tests systematically. The experimental tests show that the content of quicklime is a primarily influencing factor, and it should not be under 17% when the large content of FBCA is used. The compressive strength of autoclaved aerated FBCA blocks is reduced obviously and the dry density has not been affected too much by the content of aluminite pastes. Besides, it should be noted that the content of aluminite pastes cannot exceed 0.08%. The content of water primarily influences the compressive strength of autoclaved aerated FBCA blocks when complying with the requirements of slurry consistence in blocks production.
