Coke 95% Cathodic Protection: How Many Kilograms in 1 m³?

Hello buddies
Please help me about coke 95%. I 'm going to buy 9 m^3 coke 95% but the suppliers give me their offer in kilogram. how can I convert 9 m^3 coke 95% to kilograms?

i.e. 1 m^3 coke 95%= ??? kilograms

Hi!
converting volume to weigth you must know first the relative density.

Because the coke 95% has a lot of air and is not a constant material, it is supplied in volume and never in weight.
And it is used as the first backfilling around a cathodic anode to allow water to go around the anode and provide good contact.
Your supplier is clear not a supplier for cathodic materials, as a result if it is dirty you dammage the anode or the protecting installation.
Do not be cheap and buy real material a dammage claim from a client when they see your cheap material will kill your company.

thank you very much. that 's very useful.

I have a e book in .pdf that explains all attached
