Volcanic concrete substitutes volcanic rock for that limestone that may be burned to variety clinker. It consumes the same number of Electricity, but does in a roundabout way emit carbon for a byproduct.[100] Volcanic rock/ash are applied as supplementary cementitious elements in concrete to Increase the resistance to sulfate, chloride and alkali silica reaction because of pore refinement.
Sustainability I have constantly thought that The most crucial facet of sustainability is setting up something that lasts a very very long time. Concrete is ideal In this particular regard.
In the Ancient Egyptian and afterwards Roman eras, builders uncovered that including volcanic ash to lime allowed the combination to set underwater. They learned the pozzolanic reaction.[sixteen]
