Abstract

Ferrocement is a construction material that proved to yield superior properties in terms of crack control, impact resistance, and toughness, largely due to the close spacing and uniform dispersion of reinforcement within the material. The objective of the work presented in this research was to study the influence of several types of metal and non-metal mesh reinforcement materials on the flexural behavior of ferrocement hollow-cored panels as a viable alternative to traditional
reinforced concrete panels. Compared with the traditional reinforced concrete part, the weight of the test part is lighter. In order to strengthen these hollow-cored panels, three types of steel mesh, welded wire mesh, expanded steel wire mesh and tenax mesh with
various layers are used. The parameters investigated in this study are:
 Effect of the number of layers of mesh reinforcement provided
 Effect of the type of mesh reinforcement used An experimental plan was carried out on the test samples. Ten hollow-cored panels with dimensions of 500mm*2000mm*120mm were casted and tested until they failed under flexural load. Record and observe the deformation characteristics and cracking behavior of each sample during the loading process. Experimental results are then compared to analytical models using (ABAQUS/Explicit) programs. According to the results, high ultimate load and serviceability load, crack resistance control, high ductility and strong energy absorption characteristics have been obtained. This has the chance to be a true construction benefit to developed and poor countries. The test results of the ferrocement hollow-cored panels revealed that using double layer of expanded steel mesh as the additional reinforcement of the main steel can
achieve the best performance of the reinforced concrete hollow-cored panels. The Finite Element (FE) simulations have achieved better results in comparison with the experimental results.
