Cold Weather Thawing & Curing

Cold Weather Thawing & Curing Got You Stuck? Contractors, utility companies and precast concrete producers now have a viable solution to keep their operations and employees working all winter long.  Cold weather no longer has the upper hand in determining whether to keep your doors open or send employees home.  CureMAX insulated & heated electric construction blankets are a game changer for precast and flatwork contractors.  Get the facts on cold weather thawing & curing.

CureMAX Concrete Curing Blanket

Cold weather concrete can be established as a period of more than three days where some specific conditions occur. The American Concrete Institute under ACI 306 defies that concrete will be exposed to cold weather when the following conditions exist:

  • The average daily air temperature is less than 5°C (40°F) and,
  • The air temperature is not greater than 10°C (50°F) for more than one-half of any 24 hour period.

Cold Weather Concrete Objectives PDF

When concrete is being managed under cold weather, concrete must be protected from freezing shortly after being poured. Also concrete must be able to develop required strength for the safe removal of forms while reducing the circumstances where excessive must be applied to help concrete develop the required strength. Other important factors that must be considered are the proper curing conditions that prevent cracking and provide the intended serviceability of the structure.

Cold Weather Concrete Recommended Tips:

CureMAXFollow these steps to assure concrete in cold weather will obtain required design strength – Cold Weather Thawing & Curing:

  • Prior to pour; define the strategies that will be used including materials, forms, testing and other requirements.
  • Schedule and determine the cold weather protection measurement of the concrete mix.
  • Keep a well-define temperature record chart including concrete temperature and exterior temperature.
  • Never pour concrete on frozen ground, snow, or ice. Use CureMAX thawing blankets to maximize results.
  • Determine if special considerations and strength requirements must be met; therefore, protect concrete at specific temperatures with CureMAX.
  • If heated enclosures are going to be used when placing concrete in cold weather, be sure to know that they must be windproof and weatherproof.
  • If combustion heaters are used, vent outside to prevent carbonation.
  • Cold weather concrete should have the correct amount of air entrained voids that will resist freezing and thawing effects.
  • Concrete in cold weather is recommended to have low slump, and minimal water to cement ratio, to reduce bleeding and decreases setting time.

Try heated concrete curing blankets to prevent freezing and keep the concrete at optimal curing temperature:

  • Use insulation blankets or heated enclosures to maintain concrete temperatures above 50° degrees Fahrenheit for three to seven days.
  • Do not begin final finishing operations while bleed water is present.
  • Request a heated mix or order 100 lbs. of extra cement for each cubic yard of concrete. This extra cement helps develop early strength.
  • Fresh concrete frozen during the first 24 hours can lose 50% of its potential 28 day strength!
  • Maintain the concrete temperature above 40° degrees Fahrenheit for at least four more days after the use of the insulation blankets or heated enclosures.
  • Temperature of the concrete cannot drop faster than more than 40° Fahrenheit in 24 hours.
  • Do not seal freshly placed concrete.

It is recommended to place concrete as soon as possible, if the batch plant is too far from the concrete’s final destination, additional steps must be taken to reduce setting problems.  Hot water heaters might not be able to withstand hotter temperatures after the initial batches.

Cold Weather Concrete Temperatures –

Temperatures for placement and protect concrete in cold weather are recommended under ACI 306. The objective of the ACI 306 is to keep concrete warm, over 5 degrees Celsius, for the first 48 hours, where concrete strength development is critical. When concrete is being placed below 5 degrees, but is not below freezing point, concrete will take longer to develop the required strength. Note that removing formwork when concrete is too cold or hasn’t reached desired strength, could damage concrete strength and surfaces and concrete might collapse.

Using frost blankets and insulated formwork could be necessary to protect concrete. Insulated forms or temporary covers could provide sufficient insulation in beams, columns and walls.
