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.
