Volcanic concrete substitutes volcanic rock to the limestone that's burned to type clinker. It consumes a similar volume of energy, but does not directly emit carbon to be a byproduct.[100] Volcanic rock/ash are utilised as supplementary cementitious components in concrete to improve the resistance to sulfate, chloride and alkali silica response as a consequence of pore refinement.
