Abstract New type of reinforcement concrete has been witnessed worldwide over the past three decades. This concrete called ferrocement. It can be considered as a special case of reinforced concrete consists of cement mortar matrix reinforced with closely spaced, multiple layers of mesh or fine rods completely impregnated with cement mortar. It has been widely used in several civil structures. It may be used in buildings, bus shelters, bridge decks, concrete road repair and repair and strengthening the structure elements. Ferrocement reinforcement is a wide variety of metallic reinforcing mesh materials; woven wire mesh, welded wire mesh and expanded wire mesh. The main objective of this research is to study the structural behavior of ferrocement beams reinforced with innovative composite materials. The current work presents an experimental work to construct and test twelve ferrocement beams under three pointings loads. Some of these beams were reinforced with traditional wire meshes; expanded and welded wire meshes. In the other beams, the reinforcements were replaced with new innovative composite materials; glass fiber mesh reinforcement and polyethylene mesh reinforcement. All these beams were casted and tested under three lines loadings. All developed beams showed high strength, cracking behavior, better deformation characteristics, high ductility and energy absorption properties. Theoretical models based on the finite element method (FEM) were investigated. In this research ANSYS version 12.0 was used to study the behavior of the tested beams up to failure. Additionally comparing the results of the developed theoretical models with test results were presented. Good agreement was reached between the experimental and theoretical results. |
