Profiled deck composite slab is widely used in current construction practice. The virtue of utilizing profiled deck sheet in composite slab have been recognized for lighter, simpler, faster and economical construction. Composite slab consists of concrete, profiled deck sheet, shear transferring devices (shear connector, embossments and indentations) and light mesh reinforcement. In this paper, a review of the research carried out on profiled steel decking is given. Rigorous research is carried out on profiled deck composite slab which can be classified as experimental and analytical methods. Experimental methods include full scale laboratory tests (m-k method, SC method) and small scale tests (pull out test, push out test). Analytical methods focused on different types of mathematical techniques which are used for determine longitudinal shear strength of profiled deck composite slab. Now-a-days to improve load slip characteristics different types of concrete are utilized in composite construction. This study is also focused on different types of concrete used in composite slab. Keywords: Composite Slab, Shear connector, Slip, Concrete.
