Abstract

Present study investigates an experimental performance of mud brick wall under static lateral
load. The size of bricks was about 22×22×7 cm3 (face × bed × end). For wall specimens, two types mortar
was used: a) non-reinforced mortar, b) reinforcement mortar. For reinforcement mortar many types such as:
metal mesh (mesh size: 0.5 and 0.75 inches), polymeric mesh (mesh size: 10 and 25 mm) and palm fiber
considered was used. First mechanical properties of each types of mortar have been determined. Then the 12
wall with dimensions of 120 × 120 × 22 cm3 are made with six different kinds of mortar. Walls are loaded
under static lateral load in order to evaluate their cracks pattern, load capacities, deformability and energy
absorption characteristics. Cracks in the specimens occurred between the first and the second row that caused
the failure. The mortar was vulnerable part of conventional walls (unreinforced mortar). Ultimate strength
of walls with mortar reinforced by polymer mesh (mesh size was 25 × 25 mm) increased the load and
energy capacity to 83.04% and 158% respectively. The palm fibers increased the load carrying capacity about
82.14% and energy absorption capacity about 247%. Test result was shown that using palm fiber and polymer
mesh with diameter of 25 mm in mortar can increase adobe wall performance.
