Concrete slabs are common elements of structure in modern buildings which are often used for floor and ceiling construction reinforced by steel. The thinner ones could be used for paving the exterior under the main floor slabs or crawl spaces. They can either be supported by foundations or placed on the subsoil directly for most industrial and domestic structures.

Remove all vegetation, rocks and soft soils first so that when the slaps are placed there, they will be supported uniformly. An undisturbed and firm ground is needed for placing the concrete so it can stay properly in place. Set forms so the surfaces will slope for a minimum of two percent to provide adequate drainage in the area.
Use a lumber with the same thickness as specified for the slab as scratch template having stakes on its top surface attached. A string line can be placed also across its top of the forms to ensure proper thickness. Get a concrete with an entrained air if the flatwork will be exposed to freezing, deicing chemicals and thawing.
Minimum cementitious materials should be specified and relate it with the maximum aggregate size for ensuring a good finish and durability. Control water additions with the truck and high slump concretes should not be used. The reason is that high slump mixtures could become detrimental and will result in an increased warping because of the upper portion having greater paste content than the lower portion.
Wet concretes should not be allowed to stay in contact with your skin, enter boots or saturate clothing while placing or finishing them. Strike the surface off while you keep a small amount in front of straightedge in filling in low spots. This would help in preventing birdbaths from forming on the finished surface when they dry.
Use darby or bullfloat on the surface before the concretes are beginning to bleed or excess moisture appears to level ridges and fill voids. Any finishing operation must not be performed when bleed water is still present. Dust drying the cement is not advised when you want the bleed water to be soaked up.
Use groover in making contraction joints while the concretes are still fresh and its dept should be a quarter of their thickness. Conventional or early cut saw can be used for sawing the joints which prevents cracking if done early. Air entrained concretes

Air entrained concretes must not be hard troweled as doing so might cause the deterioration of the surface.
After finishing operation is done then immediately start curing concrete with various available methods according to what season it is. Wet curing methods must be used when freezing and thawing cycles are in the area and do it at fall. This allows drying for them to finish before first freezing arrives.
