Abstract

Ferrocement is a technical term, not to be confused with ordinary reinforced concrete.
It might be defined as a composite material consisting of a matrix made from hydraulic
cement mortar and a number of layers of continuous steel mesh reinforcement
distributed throughout the matrix. The basic parameters which characterize
ferrocement are the specific surface area of reinforcement, the volume fraction of the
reinforcement, the surface cover of the mortar over the reinforcement and the relatively
high quality of the mortar. Ferrocement behaves like reinforced concrete in its load
bearing characteristics, with the essential difference being that crack development is
retarded by the dispersion of the reinforcement in fine form through the mortar. It has
been established that when cracking takes place it results in a wide distribution of fine
cracks which, in combination with the high alkalinity of the cement rich mortar,
inhibits corrosion in the reinforcing steel.
In the experimental part In this work, Ferrocemnt plates with or withour sttiffners are
prestented for use as a retatining wall or flood protection. Theses plates are lighter than
the reinforecd concrete plates. The present study focused on the structural behavior of
thin ferrocement plates with and without frame subjected to axial compression loading.
For this objective, an experimental program was carried out and a finite element model
with ANSYS15.was adopted. A total of twelve samples thin ferrocement plates 50 mm
in thickness, 1000 mm in width and 1000 mm in length were tested under compression
loading up to faliure. The main variables taken into consideration in this paper were
ii
the type of reinforcement (reinforced bar and welded steel wire meshes), a number of
layers of steel meshes (one layer, two layers, three layers and four layers) and the
direction of load .The behavior of the tested thin plates was investigated with special
attention to initial cracking, ultimate load, the deflection under different stages of
loading, cracking pattern, energy absorption and ductility index. Good agreement was
found compared with the experimental results. The results illustrated that good
performance of the ferrocemnt plates and this may be of true construction advantages .
Main conclusions are summarized and some recommendations for practical
applications and suggestions for future research works in the field of ferrocement
concrete were introduced.
