Concrete curing is an undoubtedly crucial process of putting any structure together. Many factors rely entirely on the level of execution and could make or break the building at hand, so whatever happens, it needs to be cured accurately to create the correct traits.
The timing and the duration (which needs to be sufficient to get the job done well) are also quite fundamental. All of this can be linked directly to the concrete material’s resistance to the different types of weather, endurance, and absorbency, among other things.
Not only is it one of the low-cost curing methods, it almost creates a seal that retains moisture within the material before it has been set. It ensures that when the temperatures are high, it is locked in, and when it’s wet weather, it does not eat at the concrete, and the lower range temperatures do not leave the slab frosty. Unfortunately, this is not the best of the curing options as it is very restricted in the way you execute it. As a result, some have resorted to other methods that give more room upon implementation.
Covering With Hessian Bags or Gunny Bags
More commonly utilized for formational concrete curing, it is a method that requires consistent moisture-retaining at a specific amount. There needs to be something of a notable gap between the dampening periods, but this is also based on vaporizing quickly. The top of the concrete must remain damp, so there must always be someone monitoring this to ensure it isn’t otherwise.
Even though this is one of the more positive results attaining curing methods, it places a high demand on both labor and the water required to cure effectively. You can use more basic tools in more compact spaces to execute this, but more advanced and better machinery is required on more extensive surfaces.
The Ponding Method
This is the leading and most satisfactory method of low-cost curing used. It works better for flat surfaces as opposed to vertical ones. Small pond structures that contain water are created all around the surfaces being cured, and these provide the essential amount of water needed to carry this procedure out. Even though it fulfills the assignment, it demands a substantial amount of water and monitoring as well.
For a quicker way to get the curing done, one needs to be on high alert monitoring the temperatures used for both steam and hot water curing; they need to remain under 75 degrees and 100 degrees, respectively; otherwise, the surface may harden too quickly. If not executed properly, this may lead to inconsistency during formation and the breakdown of the concrete, forming minor fractures and crevices.
There are many rules to follow when carrying out any of these methods. However, they all have in common the accuracy of implementation to be adhered to and general affordability. Any lapse in judgment or application would undoubtedly result in a shoddy and potentially dangerous job done in the long and sometimes even short run.
