This paper presents the result of an experimental investigation on the flexural behavior of ferrocement slabs used in cold formed steel residential buildings. Experimental tests were performed on eight ferrocement slabs of size 30x 600x1200 mm simply supported along their longitudinal edges on cold formed steel sections. The slabs were tested in one way flexure under two test programs involving line loading and uniform loading. Load deflection relations obtained from the tests were used to find the first crack load and the ultimate load under both test program in addition to the developed crack patterns and failure modes. It was found that under uniform loading the slabs failed in flexure mode and carried higher loads than under line loads which failed in combined shear and flexure mode. Results showed the superior behavior of ferrocement slabs over conventional reinforced concrete slabs with regard to high strength to weight ratio, improved ductility and enhanced crack performance.
