Ferrocement is a composite material that can be used for construction of certain structures such as ships, water tanks, boats and other similar structures, where we need not use lot of resources such as coarse aggregates. This paper presents the flexure studies on ferro cement slabs, where the number of reinforcing weld mesh layers are varied as 2 layers, 3 layers and 4 layers. 6 slabs are cast, 2 each for each type of reinforcing, i.e., 2 slabs of 2 layers, 2 slabs of 3 layers, 2 slabs of 4 layers, using custom made moulds. They are tested for static and cyclic loading conditions of flexure testing after 28 days of curing. After the tests, the results are tabulated and represented graphically and analysed. It is found that, increasing the number of layers of mesh increases the flexural strength of the ferro cement slabs. Also, as the number of layers increase, the crack propagation is slow.
