An early case in point at Hoover Dam made use of a community of pipes among vertical concrete placements to circulate cooling h2o over the curing system to prevent detrimental overheating. Related techniques remain employed; depending on volume in the pour, the concrete mix utilized, and ambient air temperature, the cooling course of action may well previous For lots of months following the concrete is positioned. Different procedures are also utilized to pre-cool the concrete combine in mass concrete constructions.[126]

Hydration สหคอนกรีตอัดแรง and hardening of concrete throughout the first a few times is critical. Abnormally quickly drying and shrinkage as a consequence of elements including evaporation from wind throughout placement may possibly cause enhanced tensile stresses at a time when it hasn't nevertheless attained sufficient strength, leading to greater shrinkage cracking. The early energy in the concrete can be greater whether it is held damp throughout the curing system.
Pretensioned concrete is almost always precast, and has steel wires (tendons) which might be held in rigidity even though the concrete is placed and sets all around them.
