Concrete at the Extremes: Challenges and Solutions to Manage Concrete Placements in Hot and Cold Weather
Presented By: Dr. Jonathan Poole, PE
Abstract:
In an ideal world, concrete would only be placed on temperate, cloudy days. Reality for field concrete placements is much more complicated. The demands of typical construction schedules dictate that concrete be placed in the most extreme of conditions. In many cases, results may not be as anticipated. This presentation will give practicing engineers examples of extreme placement conditions, typical problems associated with such conditions, means and methods to mitigate the effects of extreme weather on concrete placements.
