ABSTRACT

Development of new construction materials, capable of absorbing more energy is the need of the society and this the area in which research needs. Because of the excellent behavior under flexural and impact strength, ferrocement is the widely used structural element under such circumstances. Also it has excellent mechanical properties. The thickness of ferrocement panel considered is 40 mm and 50 mm. As the thickness of the ferrocement panel is very less, M50 grade of mortar is used. The ferrocement panels are casted using galvanized welded square mesh and galvanized woven square mesh with 04, 05 and 06 mesh layers. For crack controlling, few ferrocement panels are casted using corrugated steel fibers and hooked steel Fibers in addition to the regular mesh (1% by weight of sample). The ferrocement specimens are tested under drop weight impact test. The drop weight impact test is done by dropping a weight of 3.5 Kg from a height of 0.5m and 0.75m. It is concluded that, the impact strength of the ferrocement panel reinforced with galvanized welded square mesh is excellent than the ferrocement panels reinforced with galvanized woven square mesh. When the steel fibers are added in the ferrocement panel, the energy absorption capacity of the ferrocement panel under impact loading is increased. The ductility index is found to be decreased with increase in the drop weight height.
