Quality control measures for concreting in hot weathers:

  • Cooling of aggregates.
  • Use of ice flakes in mixing water.
  • Use of low heat cement.
  • Use of admixtures.
  • Protecting fresh concrete by insulating membranes .
  • Schedule concrete placements to limit exposure to atmospheric conditions (i.e. at night or during favorable weather conditions).
