Abstract

Autoclaved aerated concrete (AAC) is a lightwt., energy-efficient, fire-retardant construction material which is used widely in Europe. Conventional AAC is produced with ground sand as the major ingredient. However, with adequate blending, AAC can be made with fly ash, a coal combustion waste material, as a substitute for ground sand. This study conducted bench-scale tests making AAC with Class F fly ash from four different sources in Illinois. AAC blocks were successfully produced to contain fly ash between 60 to 66 percent by wt. The evaluation tests indicated that their engineering properties, including d. and compressive strength met ASTM C1386 specifications for AAC wall construction units. Producing AAC using fly ash could add value to this coal combustion waste product and reduce the disposal burden to the power generation companies burning Illinois coals. on SciFinder(R)]
