In the building construction industry, how long concrete should cure before removing forms is one of the most common ones to ask. Forms are like the mold to keep the concrete in shape.
Once the concrete is poured into them, it should take a period of time to dry out. So, how long does it take before removing those forms? Find the answer down below.

Besides the information on how long concrete should cure before removing forms, you will also find other information related to the concrete’s whole drying process. Read the full information down below, and you won’t make any mistakes in removing the forms.
Here they are for you to read:
The Time for Concrete to Harden
The earliest time to remove concrete forms is 48 hours. Yes, it takes two whole days for the concrete to dry and allowing you to remove the form. It is that long because concrete should be as hard as possible and have a sturdy structure. By leaving the whole thing to dry completely within days, you can achieve that.
Factors Affecting the Length of Hardening Time
When to remove forms from concrete slab? Of course, it is when the concrete is completely hardened. Many factors can affect the length of time it takes to get the concrete fully hardened. There are several of them down below.
Temperature is a major factor affecting the hardening process of the concrete. Basically, the higher the temperature, the concrete will be faster to harden. This is why it usually takes less than 2 days for the concrete to dry in a sunny area. However, in a colder area where sunlight is scarce, and the temperature is always low, the drying process can be slower.
- Size of the Concrete Member
The largest the concrete member, the slower it takes to dry. It is like a common explanation as you have to wait longer for the whole thing to dry out when the surface to dry is massive. This is why in large-scale building construction, the concrete forming will be done first as it the longest to dry.
- Grade of Cement
In installing the concrete, you need cement. The cement has different grades, and the higher the grade, the faster it dries. However, it is usually the expensive type of cement that has the fast-drying feature. It does not really matter, though, as the concrete needs to be left to dry at some points.
You will have to figure out everything about the form removal from the information up above. They are quite helpful and will definitely inform anyone looking for the answer. Even when you are not a professional, you can still install a concrete slab at home.
Using the help of those explanations on how long concrete should cure before removing the forms above, you can do the job even easier.
