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 select this because of their inexpensiveness as well as it gives durable and attractive surface which could be maintained easily. Your company may be one of those using concrete slabs Mandeville for their business in construction. Here are some details which can help you to build quality projects in cities such as Mandeville, LA.
First, remove all rocks, soft soils and vegetation so that the slabs are uniformly supported when put there. Place the concrete on firm, undisturbed ground if ever possible so that it could stay in place properly. Set forms so their surfaces would slope for at least two percent in providing adequate drainage to the area after.
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 to make contraction joints while concretes are fresh still and the depth should be quarter of its thickness. Conventional saw or early cut one can be used in sawing the joints that prevents cracking when done early. Concretes with an entrained air must not be steel troweled as this might cause the surface to deteriorate.
After completing the finishing operation then start curing the concrete immediately with different methods available depending on the season. Wet curing methods should be used when the area have thawing and freezing cycles and you placed them during fall. This allows them to dry before the arrival of first freeze and deicing agents are not advisable at the first winter.
