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.
Most contractors choose them for their attractive and durable surface that could be easily maintained and their inexpensiveness. Your company might be one among the users of concrete slabs Mandeville meant for your construction projects. Here are some things to know in helping your projects in cities like Mandeville, LA to be built with quality.
Remove first all soft soils, vegetation and rocks for the slabs to be supported uniformly when putting them there. Place the concrete at a firm and undisturbed ground if possible so it could properly stay in place. Set forms to let their surface slope for two percent at least in providing the area of an adequate drainage.
Use a lumber that are as thick as the specified one for a slab as a scratch template with stakes attached to its top surface. A string line could also be placed across the top of these forms in ensuring proper thickness. If the flatwork would be exposed to thawing, freezing and deicing chemicals then get an air entrained concrete.
A material that has minimum cementitious should be specified with relation to the maximum aggregate size to ensure the durability and finish is good. Do not use high slump concretes and control with the truck the additions of water. Because high slump admixtures can become detrimental and result with an increased warping due to a greater paste content at the upper portion compared to the lower one.
Wet concretes saturating clothing, contacting your skin, and entering boots must not be permitted while you place or finish them. Strike off the surface while keeping a small amount at the front of straightedge for filling low spots in. This will help in preventing the formation of birdbaths when the finished surface gets dry.
Darby and bullfloat are to be used before the concretes begin to bleed on the surface or excess moisture will appear in leveling the ridge and filling voids. And any finishing operation should not be done if bleed water is present still. Dust drying cement is inadvisable when you need to soak up the bleed water.
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 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.
