How To Calculate Slope In Concrete Slab
Let the slope gradient for a slab is taken as 1:100. Now, you have to estimate the slope
Now put 1000 in place of 1. Now, divide it with 100 i.e. 1000/100 = 10 mm.
If distance is 6 m then 1/100 = V/6
so , v = 6/100
v = 0.06 meter , convert it in millimeter
v = 60 mm means 10 mm slope in Every 1 Meter
It shows that for every each 1 m extent, the slope of 10 mm can be arranged.For more Example watch video on it you get the link of the video at the end of the post.
some common slopes are mainly used as below in table :-
