The term spalling is used to refer to the cracking that occurs in concrete. This damage can be caused by freeze-thaw cycles as well as expansion reactions. Learn Formwork Packages Info
It is never a good idea to pour concrete over frozen ground. In order to pour concrete in temperatures like this, use a heater to melt the ground you plan on filling and maintain the heat while the slab cures. Visit: Formwork Packages Page!
Plastic coverings help with protecting the fresh surface, but also aid in smoothing and safely curing the pour. Because the concrete dries slower beneath the plastic, there is less chance of cracking during the curing process. Visit: Formwork Packages Page!
For maximum curing speed, one trick would be to use warm water when mixing the powder. This hastens the chemical reactions, but beware of using water that is too hot, because of possible damage. Visit: Formwork Packages Page!
As long as you leave some rebar sticking out of the pour, you can take multiple days to complete the project. Just know that the concrete will already have more than begun to set by the second day. Read more: Formwork Packages Information!
As soon as the concrete is poured, it is to be kept wet for 28 days. This can be accomplished by spraying the slab as often as possible every day to keep it saturated completely for the best curing process. Read more: Formwork Packages Information!
While it is not illegal, professionals recommend waiting at least 7 days before driving on a concrete slab, because after a week, the concrete has achieved 90% of its maximum strength capacity. Read more: Formwork Packages Information!
Chicken wire is very similar to the wire used in standard mesh reinforcements, so it is completely safe to use. When reinforcing a concrete structure, chicken wire can work very well, but it is not to be used in high-stress or industrial situations. Read more: Commercial Concreting Information!
Clay is not a good base for concrete, because it will likely depress into the ground over time and lead to the sinking of the structure. It can also pull moisture from the concrete itself and cause various brittle areas across the surface. However, as long as the area is prepared carefully, building on clay
