An early case in point at Hoover Dam utilised a network of pipes in between vertical concrete placements to circulate cooling h2o during the curing system in order to avoid harming overheating. Equivalent methods are still utilized; based on quantity with the pour, the concrete combine made use of, and ambient air temperature, the cooling process may perhaps previous For numerous months following the concrete is put. Several approaches are also used to pre-interesting the concrete combine in mass concrete constructions.[126]

This will tremendously reduce the excess weight of beams or slabs, by
Treatment will have to also be taken to avoid freezing or overheating mainly because of the exothermic placing of cement. Incorrect curing could cause spalling, diminished power, lousy abrasion resistance and cracking.

This reusable mold is taken to the managed atmosphere and cured, which implies to supply the sufficient amount of humidity, along with The best temperature, for the concrete mold to attain the required results.
The crucial element to acquiring a solid, resilient concrete rests within the mindful proportioning and mixing from the ingredients. A concrete combination that doesn't have plenty of paste to fill every one of the voids between the aggregates will be challenging to here area and will create tough, honeycombed surfaces and porous concrete.
Pervious concrete delivers important environmental Advantages since it lowers the necessity for drainage facilities. Additional it facilitates the recharge of floor drinking water along with the filtration approach purifies the water as it percolates down below.
