Abstract: Autoclaved aerated concrete (AAC) is important, building materials which has unique physical and mechanical properties compare with normal concrete. In this research silica fume used as the chemical additive to increase compressive strength, the percentage of silica fume added in this study is (4, 8, 12 % and 16% by weight of cement that used in recipe) the result shows the compressive strength increased with increasing silica fume to a specific limit than the compressive decreased with an additional amount of silica fume. It has been found that the density are not affected with silica fume due to less amount of silica compare with the total amount of the mix, and for thermal conductivity the same behavior was shown for the same reason as the lack of density.
Keywords: AAC, Autoclaved aerated concrete, cellular concrete, Silica fume.
