The first application of Raman microscopic imaging for studying cementitious materials revealed the distribution of crystalline, polymorphic, and amorphous phases in Roman cement binder remnants (resolution ≈ 500 nm), the complex composition of added blast furnace slag, and the identity of pigment particles in historic artificial stone. On the basis of these results, we discuss advantages of Raman imaging over ‘point-spectroscopic’ measurements and the potential of this method to extend the arsenal of analytical tools applied to study historic building materials so far.
