You’ll also want monitoring equipment to make sure you stick to your desired cold weather concreting specification. Depending on what it is, you may have to prevent the concrete temperature from going below a specified value during placement and curing. You may also need to keep the differentia...
Handling bleed water: Wait until all bleed water has evaporated before finishing. Concrete poured and placed in cold weather has a much slower setting and curing time, so bleeding will start later than expected. Be prepared to handle more bleed water than is typical in regular concrete placement...
How does cold weather affect your health?The article offers information on the weather-related problems that will rise during the cold weather which include the skin, body temperature, and immune system.EBSCO_AspHarvard Health Letter
Temperature evolution and compressive strength prediction of early age concrete are of great interest for designers and contractors in cold weather. In this study, a calculation method based on a C# program was first put forward to estimate the temperature evolution of concrete with thermal insulation...
Fresh and hardened concrete properties differ significantly depending on the used chemical admixtures. Calcium chloride has been known for decades as an antifreeze agent which not only accelerates strength development during cold weather, but can also improve the rheology. However, it also negatively imp...

3.5. Adaptability of ABC to Cold Weather Countries with cold or northern climates are exposed to arid weather in winter. Structures made of concrete deteriorate mainly due to freeze/thaw actions. Indeed, a concrete structure can suffer damages such as surface spalling caused by its exposure to fr...
Some solutions may help in adapting to cold weather by altering the chemical properties of concrete, as, for example, with the use of accelerators, allowing for an increase in the initial resistance of concrete and improving its behavior against freez- ing [50], or with the use of antifreeze...
