An early instance at Hoover Dam employed a community of pipes between vertical concrete placements to circulate cooling h2o in the course of the curing course of action to stop harmful overheating. Identical devices are still employed; according to volume in the pour, the concrete mix utilized, and ambient air temperature, the cooling course of action may possibly last For lots of months following the concrete is positioned. Various methods are also utilized to pre-great the concrete blend in mass concrete buildings.[126]
High reactivity metakaolin (HRM): Metakaolin provides concrete with power and longevity comparable to concrete manufactured with silica fume.
