Volcanic concrete substitutes volcanic rock to the limestone which is burned to form clinker. It consumes an analogous degree of Electrical power, but does not directly emit carbon to be a byproduct.[one hundred] Volcanic rock/ash are utilized as supplementary cementitious elements in concrete to improve the resistance to sulfate, chloride and alkali silica response as a result of pore refinement.
Another innovation in masonry design is using prestressed concrete. It's obtained by either pretensioning or posttensioning procedures. In pretensioning, lengths of steel wire, cables, or ropes are laid from the vacant mold then stretched and anchored. Once the concrete has long been poured and permitted to established, the anchors are launched and, because the steel seeks to return to its original length, it compresses the concrete. During the posttensioning system, the steel is run through ducts shaped inside the concrete.

All portland cements are hydraulic cements that set and harden by way of a chemical response with drinking water.
