How to measure self weight of RCC slab
In this construction video tutorial, the renowned engineer Sami Ullah shows some simple processes to work out the self weight of RCC slab to make the RCC slab design process uncomplicated.
Initially, it is required to compute the thickness of RCC slab. Suppose, the thickness is taken as 6 inches or 0.5 feet.
To determine the self weight of RCC slab, the following formula should be applied :-
Self weight of RCC slab = Density of RCC x Thickness of slab
Now, it is necessary to find out the density of RCC slab as follow :-
Density of RCC = 68.15 kg/ft3 or 150.23 lb/ft3
After putting the above value in the formula, the following result is obtained :-
Self weight of RCC slab = 150 x 0.5 = 75 lb/ft2
If it is required to calculate the total weight of the slab, then area of the slab should be measured first.
Suppose, total area of the slab = 200 square feet
So, total self weight of the slab = self weight x total area of the slab = 75 x 200 = 15000 lb/ft2
