  • Unneeded water will lower concrete’s overall strength.
  • Can lower durability and increasing possibility for drying shrinkage.
  • Can reduce water tightness.

Placing concrete in hot weather can become troublesome. Water demand is increased and set times become faster. Here are a few hot weather concreting tips:

  • Use of chilled water in the mix is recommended. This reduces concrete temperature.
  • Addition of retarding admixtures. This will provide additional set times.
  • Dampen subgrade and wood forms. Doing this will discourage water loss from the concrete.
  • Start curing immediately after finishing.
  • Avoid clear plastic covers.

Like hot weather, placing concrete in colder temperatures can alter the characteristics of concrete during placement. Concrete will set slower in colder temperatures.

  • Thaw frozen ground before placing concrete. The ground can pull the heat from the concrete.
  • Addition of accelerating admixtures. Accelerators speed up set times.
  • Use of hot water in the concrete mix. Works well with accelerators.
  • Do not rush form removal. Colder temperatures require more time to hydrate.
