An early illustration at Hoover Dam utilised a community of pipes amongst vertical concrete placements to circulate cooling water during the curing process to avoid harming overheating. Very similar units are still utilized; depending on quantity on the pour, the concrete mix made use of, and ambient air temperature, the cooling course of action could very last For a lot of months following the concrete is placed. Several methods also are accustomed to pre-neat the concrete mix in mass concrete structures.[126]
Air entraining agents include and entrain small air bubbles during the concrete, which reduces problems throughout freeze-thaw cycles, raising durability. Nonetheless, entrained air involves a tradeoff with energy, as Each and every one% of air may lessen compressive power by five%.
