RE: [Strawbale] Concrete Base - foundations question??
Hi Kurt,
what i know is that if a steel ship is moored for a long
time (a year or so) in the same direction it gets magnetised in the same
direction as the earth magnetic field. To let the compasses work well the ships
then need to be demagnetised. So parallel i guess that the steel in concrete
will also adapt to the local magnetic fields and over time, like a cameleon,
have the same properties as the land beneath.
The good thing of steel is that it does shield off lots of
electro magnetic radiation. so for that reason i might rather use some steel in
my straw walls rather then to be afraid of magnetic disturbances. However i'm
not very experienced with devining and i'm sure a sourcer can tell you more
about this

if you want to use concrete, you should think about the iron that you usaly
us in the concrete. This iron can extremly change the magnetic field of the
earth!!! And i dont belive that this is good. Some people made experiments with
straw fibres or littel metal fibres.
wish you all the best....
Kurt
