Abstract

Autoclaved aerated concrete (AAC) is a lightweight environmentally friendly concrete

made from cement, sand, lime, water, and aluminum powder. Having a crucial interest for

the last decade, due to their low density and thermal properties. This study shows the effect

of sisal Fiber on the density and compressive strength of AAC blocks. Therefore, three

groups of samples were produced, with fiber contents of 0.1%, 0.2%, and 0.3% of total

volume. The study's results show that AAC reinforced with sisal fibers had a density between

652 and 731 kg/m3. However, 0.2% represents the optimal fiber content for achieving the

highest density. Furthermore, the compressive strength recorded 3.23, 4.09, and 4.17 Mpa

for fiber contents of 0.1%, 0.2%, and 0.3%, respectively. Based on the results, it can be

concluded that the AAC reinforced with sisal fiber significantly improved the density and

compressive strength of AAC specimens. This type of AAC is suitable for partition and non-

load-bearing wall applications.
