Taguard Real Time Probe Based Data logger is a ideal product to be used for monitoring concrete curing
What Temperature Should Be Maintained?

At the batch plant, concrete should be kept at 45 to 70 degrees, with the higher end of that range required for thinner concrete pours and colder outside air conditions. Lower temperatures in that range are acceptable at the plant if the air temperature is less severe and if the pour will be thicker. Upon pouring and throughout curing, the concrete must be kept at 40 degrees if more than 72 inches thick, 45 degrees if 36 to 72 inches thick, 50 degrees if 12 to 36 inches thick, or 55 degrees if less than 12 inches.

Here are a few more temperature tips that should guide any cold-weather concrete work:

The surface, edges, and corners of the poured concrete are the most susceptible to cold and the most critical to protect.

Rebar of No. 18 and smaller can be less than 32 degrees upon installation. So can formwork and steel I-beam and other embedments smaller than 4 inches square.

However, surfaces in contact with the fresh concrete must be free of ice, snow, and frost, and concrete must not be placed on frozen subgrade. Hydronic (water or steam) heating tubes can be placed directly on the subgrade or on top of insulating blankets placed on the subgrade to thaw the subgrade before the pour.

How Do You Protect Concrete From Severe Temperatures?

Here are the best protection methods to insulate curing concrete from cold ambient air:

Because concrete throws off heat during the chemical reactions of curing, insulated blankets and insulated formwork can be sufficient to maintain proper curing temperatures. They must be secured so that wind cannot blow them off. It is also important not to trigger thermal stress through overheating resulting from overinsulation.

Strong, weather-proof, heated enclosures protect concrete within buildings, but curing membrane or additional water may be needed to prevent the surface from drying due to the use of heaters.
