An early illustration at Hoover Dam applied a network of pipes involving vertical concrete placements to flow into cooling water in the course of the curing process in order to avoid damaging overheating. Similar units are still applied; determined by quantity on the pour, the concrete combine utilised, and ambient air temperature, the cooling approach may well last For numerous months once the concrete is positioned. Several methods are also utilized to pre-cool the concrete blend in mass concrete structures.[126]
