Carbon fibre in conductive concrete has a very low density. i.e 1.8 to 2.0 g/cm^3
PAN (polyacrylonitrile) carbon fibres has a range of 1.75 to 1.93 g /cm3.

It is between 0.5% to 1% by volume.
It’s better to use density by volume and not by weight because 0.5% to 1% by volume is necessary to maintain electrical conductivity properly. The weight density will then depend on the fibre used. That will fall between 1.5 to 2 g/cc.

Conductive carbon fiber reinforced concrete is a self-heating material specially used for prevention against ice formation.
Following are the specification of Carbon fibre used in conductive concrete;
