FR05 - How to Handle Hot- and Cold-Weather Concreting

Friday, January 24 from 8:00 AM to 11:00 AM | Room N232, North Hall, Las Vegas Convention Center « Back

Don't let hot, dry and windy conditions or freezing temperatures steal your profits! First, hear how weather conditions affect fresh and hardened concrete properties and the required protection necessary. Attendees will learn how to handle problems such as slump loss, plastic shrinkage cracking, crazing, rain showers, and freezing temperatures during placing, finishing and curing operations. Why air entrainment can't fully protect freshly placed concrete against freezing temperatures will also be addressed.

  1. Identify how weather conditions affect fresh and hardened concrete properties including workability, time of setting, finishability, strength, cracking and required protection
  2. Discuss how to handle slump loss, plastic shrinkage cracking, crazing, changing set times, rain showers and freezing temperatures
  3. Analyze effect of temperature during placing, finishing and curing operations
  4. Recognize why air entrainment can't fully protect freshly placed concrete against freezing temperature
