But there are some factors which you must consider before opening your shuttering work. The first thing that comes is the grade of cement. That is, if you take OPC 43 or 53 grade of cement, it also depends on what will be your shuttering removal time. After that, it also depends on the temperature and as I told you earlier, the type of cement, that is, whether you are using OPC or PPC, your shuttering removal time also depends on it. And finally comes the grade of concrete. You will also have to keep in mind that it also depends on the grade of concrete
Now if we talk about the houses that are built, you must have noticed that it does not happen that if your span is 14 feet, you will remove only its shuttering work and keep the rest of the shuttering work as it is. The contractor removes his shuttering work completely after coming. So what should you do? You should wait for at least 14 days to 21 days remove the shuttering work of your slab.
The advantage of this will be that the ponding that you have made on the roof, will allow the slab to get water properly.
