English Abstract
Ferro cement is the name which is given to a certain type of composite material ; its matrix consists of rich cement mortar and its reinforcement consists of superimposed layer of wire mesh with and without skeletal steels in between.
Ferro cement makes excellent water containing structures, barges, boats and others.
To fully realize its potentials, it is important to understand its cracking behaviour.
This investigation is devoted to study the fracture behaviour of Ferro cement beams under flexural loading.
The influence of different factors on the strength and deformation characteristics is examined and assessed.
The factors studied are the volume fraction of mesh reinforcement, presence of initial crack, and alignment of mesh layers.
A series of 8 bending specimens reinforced with square wire meshes were tested under two central concentrated loads.
Deflection, mouth opening displacement, crack width, and crack length were recorded from the first application of load up to failure.
A finite element program for analysis of beams has been developed to calculate the resulted deformation, and a fracture program has been developed based upon the linear elastic fracture mechanics equations to estimate the stress intensity factor.
A comparison between the theoretical and experimental results has been made.
The results appear to have good agreement.
The calculated stress intensity factor for specimens with high volume fraction of mesh reinforcement reached to about (40MPa.
mm1 / 2), while for specimens with low volume fraction it was (12MPa.
mm1 / 2).
