Despite the fact that experts say a concrete mix that is well made will stay on, there are a lot of factors that govern the strength of concrete. Mix designing, batching, transportation and placement are all important for the optimum results that you might want to see in concrete construction. While everything else is absolutely manageable, the art lies in the placement of the concrete on to the surface where it needs to be installed. The experts from Staten Island divide cement work placement on the basis of the situation and suggest the things that need to be taken care of in a particular manner:
- Foundation concrete: When placing the foundation concrete below the ground then the first that needs to be done is the removal of the loose earth from the bed. In case there are any roots of nearby placed trees passing through the foundation then they must be cut off in order to prevent any further development through the foundation that can develop cracks in the future. It is a mandate to wet the ground so as to prevent the concrete water from getting absorbed into the ground.
- Concrete road slab or air slab: Concrete should be placed in bays after the removal of any stuff from the ground that can hamper the strength of the concrete in future. This includes any kind of loose earth or roots and grass that has the tendency of growing wildly even through the concrete structure. Placing the concrete in sufficient quantity is always a better idea than placing in heaps and then attempting to spread the same.
- Dams, abutment, and pier: The placement of concrete should be done in layers that are 20 cm to 30 cm in length. Cement work experts from Staten Island suggest that any cold joints in between the surface of concrete should be completely avoided. Compaction, the next level of concrete construction, should be done keeping in mind vibrators is your best bet in this case of work. The successive layers should be placed with great expertise when building dams so that they can retain all the pressure.
