The form of a reinforced concrete and a vital structural element is used to provide flat surfaces (floor and desk) in buildings. Based on the support of the beam and the ratio of the openings, the slabs are generally classified into fusions, one-way and two-sided. Different terms and conditions for choosing suitable and affordable concrete slabs are requested according to the type of building, design architecture, aesthetic feature and length of the width. For this reason, concrete boards are classified into one-way folding, flat slabs, flat sheets, waffle sheets, core slabs and crowns, toothed slabs, slabs in grade, hardboard slabs and composite slabs. This method used in the form of a single-side board construction on beams that include fixing and burning with the installation of reinforcements, and eventually pouring concrete refills of a single-sided board suitable for a width of 3-6 meters can also be used for larger larger at relatively fair cost Higher and more radial deviation. However, additional boards are required for the beams
