Refer the material properties in PDE interfaces

Hi all,
I have defined materials and their properties from the built-in library already. While working on the coefficients of the PDE interfaces ( for example, Coefficient Form PDEs), can I just use those predefined material properties? If yes, how do I know their variables names?
Specifically, I have defined concrete in the Material section. When working on coefficient form PED, I want to use the concrete density times concrete specific heat, which are already defined in Materials, as the damping coefficient. Should I use something like Materials.rho*Materials.Cp? What variable names should I use?
Thanks for any suggestions.
