Coal is only used for burning the klin to 1400°c to produce the concrete. The other method to produce concrete is by fly ash. Which again is not coal but a by product of burning coal which flies out and is collected using electrostatic precipitation. So whatever coal floats your boat to reach 1400° or to make fly ash will serve the purpose.
Ash aggregate may also be used as conventional aggregates for use in asphalt, concrete, and road construction. Bottom ash may also be used as raw material in the manufacture of portland cement and as fill material. Power plant bottom ash is very versatile .
