Cold Weather Concreting

Cold weather can lead to many problems in mixing, placing, and curing of concrete that can have an adverse effect on its properties and service life. This session has been developed to assist the entire construction team (owners, specifiers, contractors, and ready-mixed concrete producers) in the design, manufacture, delivery, placement, and curing of quality concrete in cold weather.

This session will discuss:
1. The effects of cold weather on concrete on set time and compressive strength
2. Concrete materials and mix design considerations
3. Use of accelerating admixtures and their effects on set time, corrosion, water demand, workability, and strength gain
4. The differences between calcium chloride and non-chloride admixtures and their use in sub-freezing conditions
5. Control of plastic shrinkage cracking
6. Cold weather curing practices, finishing problems and construction solutions
