Volcanic concrete substitutes volcanic rock for the limestone that's burned to form clinker. It consumes the same quantity of Strength, but does circuitously emit carbon to be a byproduct.[one hundred] Volcanic rock/ash are used as supplementary cementitious components in concrete to Enhance the resistance to sulfate, chloride and alkali silica reaction on account of pore refinement.
Concrete roads are more gasoline successful to push on,[132] far more reflective and previous significantly more time than other paving surfaces, but Possess a much smaller market place share than other paving remedies.
