For some construction applications wood has been largely replaced by concrete do you think concrete is mechanically homogeneous?

Solution

Yes wood is replaced by concrete because of mechanical properties .

Chemically if we consider concrete is heterogeneous composite material consisting of cement water fine and coarse aggregates.

Cement may be called mechanically homogeneous but not concrete

As homogeneous material should possess same properties in all directions whereas it shows uncertainties in case of

Concrete.
