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. |
