Calculating the amount of concrete
Calculating the amount of concrete Foundation In order to know the amount
of concrete, you will first need to calculate the volume of the foundation
slots. You multiply: the length of the outer foundation wall the depth of
the outer foundation wall the height of the foundation Do the same for the
inner foundation wall and subtract both outcomes. Multiply the needed
volume by the number of kg of components, knowing that you will need for
approx. 1 m³ of concrete with concrete strength of 250 kg/m³ mortar and a
proportion 1 : 3 : 4 you will need the following: Portland cement ( CEM I
and class 32,5): approx. 250 kg Rhine sand 0/2: approx. 750 kg gravel
(aggregate size 4/14): approx. 1000 kg Example (by means of building plan):
length outer foundation wall = l(a) = 1,69 m length inner foundation wall =
l(b) = 1,09 m depth outer foundation wall = d(a) = 1,69 m depth inner
foundation wall = d(b) = 1,09 m height of the foundation = h = 0,60 m (l(a)
x d(a) x h) - (l(b) x d(b) x h) = volume...
