The On-Demand Course: Cold Weather Concreting: What to Prepare to Keep Concrete Construction Continuing is a recorded webinar, part of the numerous, valuable resources by the American Concrete Institute (ACI, www.concrete.org) on cold weather concrete — concrete properties and the construction operations of mixing, transporting, and placing of the concrete materials in cold weather.
The American Concrete Institute highlights how concrete construction in cold weather and low temperatures are concerns for both the contractor and owner. During concrete construction in cold weather and low temperatures, a lack of proper protection of concrete leads to damage. However, the American Concrete Institute notes that over-protection of concrete, during low temperature weather events, inflates costs, undermines budgets, and causes overruns.
Cold weather concreting practices are one of many areas where weather planning by the contractor and owner improves risk management, supports on-time schedules, and drives on-budget delivery. The on-demand webinar provides guidance to assist in judging the appropriate actions and precautions for concrete construction in cold weather and low temperatures using 306R-16: Guide to Cold Weather Concreting.
The four learning objectives of the On-Demand Course: Cold Weather Concreting are to:
- Understand the challenges with cold weather concreting operations;
- Identify the performance based options for concrete subject to cold weather temperatures;
- Be prepared to establish a cold weather plan and build on contingency plans, and;
- Identify industry options for guidance to assist in judging the appropriate actions and precautions.
