Pouring Concrete in Cold Weather - thebalancesmb.com
Schedule and determine the cold weather protection measurement of the concrete mix. Keep a well-defined temperature record chart including concrete temperature and exterior temperature. Never pour concrete over frozen ground, snow, or ice. Use heaters to thaw the ground before pouring concrete.
Placing Concrete In Hot Or Cold Weather | Sakrete
Almost everything in this discussion on hot weather is directed at someone pouring a slab. If you are mixing up concrete and placing it in a hole to support a fence post of deck, hot weather normally isn't a problem. If the concrete is setting too fast to place in the hole, then using cold mixing water or ice will help.
Cold and Freezer Floor Concrete Repair | Roadware Incorporated
In cold environment, the cure time depends on the temperature of the material, the temperature of the sand or aggregate if used, the volume of the repair, and the temperature of the concrete. Below is a chart of approximate cure times at various temperatures and conditions.

Guide to Hot Weather Concreting Reported by ACI Committee 305 ACI 305R-10 Environmental factors, such as high ambient temperature, low humidity, high wind, or both low humidity and high wind, affect concrete properties and the construction operations of mixing, transporting, and placing of the concrete materials.
PDF CIP 12 - Hot Weather Concreting
In the case of extreme temperature conditions or with mass concrete, the concrete temperature can be low-ered by using chilled water or ice as part of the mixing water. The ready mixed concrete producer uses other measures, such as sprinkling and shading the aggre-gate prior to mixing, to help lower the temperature of the concrete.
