ABSTRACT
Autoclaved Aerated Concrete (AAC) block are used mainly as non-load-bearing walls that
provide heat insulation. This results in considerable saving in cooling energy particularly in
hot desert environment with large variation of daily and seasonal temperatures. However, due
to the relatively low strength there use load bearing walls is limited to single storey and low-rise
construction. A system to enhance the strength of the AAC masonry wall in resisting both inplane
vertical and combined vertical and lateral loads using ferrocement technology is proposed
in this research. The proposed system significantly enhances the load carrying capacity and
stiffness of the AAC wall without affecting its insulation characteristics. Ferrocement is made of
cement mortar reinforced with closely spaced wire mesh. Full scale wall specimens with height
of 2100mm and width of 1820mm were tested with different configuration of ferrocement. A
finite elementmodel is developed and verified against the experimentalwork. The results of the
finite element model correlates well with the experimental results.
