Structural Behavior of Light Weight Ferrocement Columns

Zeinab A. Etman

Abstract


This paper presents the results of the behavior of reinforced ferrocement light weight columns by permanent precast lightweight ferrocement hollow blocks. For this objective, an experimental program was carried out extensively and finite element models with ANSYS 14.5 were conducted. The program of the experimental constructed and testing of sixteen columns of total dimensions 450×650×250 mm consisting of 3 permanent precast lightweight ferrocement hollow blocks having the dimensions of200×400×200 mm filled with core material. Two types of light weight ferrocemnet hollow blocks were used to construct the columns. Two types of single layer welded steel mesh and glass fiber mesh were used as a horizontal connection between the permanent precast lightweight ferrocement hollow blocks. The core material was investigated: one layer of welded steel mesh embedded in the matrix. Welded steel mesh with single and double layers was used to reinforce the plastering layer as a bonding layers forms; namely welded steel mesh. Shear connections between the permanent precast hollow blocks and the core material were investigated called; shear connector. The columns were tested under uniform load. The behavior of the columns was compared. The results showed that an improvement in the cracks resistance, serviceability loads, ultimate loads, and energy absorption. Theses results were verifies the validity of the proposed model. Good agreement was found compared with the experimental results. Out of this research, this paper presents applications of  using light weight ferrocement  units in construction of low-cost housing which are very useful for developed and developing countries alike with great economic advantages.
