The paper presents the experimental study on Ferro foam concrete I beam with different number of wire mesh layers. Ferro foam concrete is alternative materials, which consist of a combination between wire mesh and foam concrete. This material is lightweight and easy to be produced. There are 3 specimens has been tested. Specimens’ configuration was 300 mm height, 150 mm width of upper and lower flange, and 60 mm web with 2200 mm span. The different between specimens was number of wire mesh layers, 2 layers, 3 layers, and 4 layers. Foam concrete used in this research consists of cement, water, foam agent, and 10 % Pozzolan. Compression strength of concrete was 23.23 MPa, and Tensile strength of reinforcement D8 and wire mesh G12.7 were 421 MPa. The specimens were tested using four points loading. Three units of LVDT were placed at a distance of 250 mm and 1000 mm from the support. Based on the results, it was found that the maximum load that can be carried out by specimen was 8.48 Tonf, 8.00 Tonf, and 9.50 Tonf, for 2 layer, 3 layers, and 4 layers, respectively. Maximum deflection for each specimen was 14.01 mm, 13.53 mm, and 21.37 mm, for 2 layers, 3 layers, and 4 layers, respectively. Number of layer in I beam 300.60.60 has no significant effect for the beam in their ability to carried the load.
