Rancho Mission Viejo
Under the guidance under ACI 306 by American Concrete Institute, cold weather concrete refers to a period of over three days where there are specific conditions :
- Below 5 degrees Celcius (40 degrees Fahrenheit)
- Below 10 degrees Celcius (50 degrees Fahrenheit) for 24 hour period
In Rancho Mission Viejo, our top contractor is San Clemente Concrete Pros. We guarantee intricate care with pouring concrete under cold conditions. Our contractors will ensure that concrete doesn’t freeze immediately.

The concrete should also develop the necessary strength so that forms are safely removed while minimizing the need to apply excessive heat and for the concrete to develop the necessary strength. Some other key factors when curing can hinder cracking and provides the structure’s serviceability.
How To Pour Concrete During Cold Weather
In order to get durable concrete when pouring in cold weather, here are the following steps.
- Prior: Define strategies including the materials, testing, forms, and other requirements
- Plan the measures you to protect from cold weather the concrete mix’s measurement
- Record temperature chart of the concrete and environment
- Avoid pouring on frozen ground, start by thawing the area using a heater before you pour concrete
- Determine specific strengths and considerations. Ensure that the concrete is protected at certain temperatures.
- When pouring concrete in freezing weather on concrete pavers or other concrete projects, ensure to weatherproof any heated enclosures.
- When concrete is poured in cold weather, it should have a low slump. The water to cement ratio should be minimal to minimize bleeding and to decrease the settling time.
- Prevent the carbonation of combustion heaters when used.
- Resist freezing by placing the right amount of air entrained voids.
- Use concrete curing blankets to avoid freezing.
- Guarantee concrete temperature remains over 50 degrees, use heated enclosures or insulation blankets
- Don’t start the final finishing operations if there is bleed water
- Ensure that you have a heated mix or ensure that you order 100 lbs for every cubic yard of concrete. The extra cement will go a long way in helping to develop early strength.
- Ensure that the concrete temperature is maintained at an average of 40 degrees Fahrenheit for a minimum of four days after using the heated enclosures or insulation blankets.
- When concrete is sealed freshly, don’t seal it until it is bleeding and the settling process has started.
- Concrete should be placed the soonest possible
- Water heaters may be unable to withstand hotter temperatures once the initial batch is over
How to Maintain A Concrete Temperature in Cold Weather
When concrete is placed at a temperature of below five degrees but hasn’t reached freezing point, it will take time before it reaches the desired strength. If the formwork gets removed when the concrete is too cold or hasn’t reached the required strength, this could affect the concrete strength. Both concrete and the surface might end up collapsing. Using insulated formwork and frost blankets may be required to protect concrete.
As you may realize, pouring concrete in cold weather areas is challenging. This is why you need to work with a qualified Rancho Mission Viejo concrete contractor.
