An early case in point at Hoover Dam utilized a community of pipes involving vertical concrete placements to circulate cooling drinking water throughout the curing approach to stay away from detrimental overheating. Identical programs are still used; based upon volume from the pour, the concrete blend utilised, and ambient air temperature, the cooling approach may perhaps past For several months once the concrete is placed. Numerous solutions also are used to pre-neat the concrete combine in mass concrete constructions.[126]
After the Roman Empire, the use of burned lime and pozzolana was drastically lessened. Small kiln temperatures during the burning of lime, deficiency of pozzolana, and bad mixing all contributed to your drop in the caliber of concrete and mortar.
