How cold can it be before concrete cannot be poured? How about heat? Concrete can endure many different temperature ranges. There are many precautions one can take when pouring concrete in either range of temperatures. However, concrete temperature testing is needed to ensure proper curing. Curing refers to the process when moist concrete hardens into a more solid and strengthened state.
Preventative Measures
It is important to keep in mind the ambient temperature. Yet, it is even more important to know how to keep the concrete at the right temperature while it cures. During cold weather, many people use heated enclosures or insulated blankets to prevent the concrete from freezing. Conversely, many people use windbreaks, sunshades, and evaporative retarders (spray applied to surface of concrete after placement to hold in moisture) when it is hot.
There are other methods too, but these are just a few.
Temperature Ranges
Based on many expert opinions, the best temperature to pour concrete is between 40 degrees Fahrenheit and 60 degrees Fahrenheit.
When the temperature drops below 40 degrees Fahrenheit, the chemical reactions that strengthen concrete slow down and can lead to weaker concrete. Additionally, if temperatures drop below freezing, the water inside the concrete can freeze and expand, causing cracks.
Hot temperature is generally anything above 90 degrees Fahrenheit, including low humidity and high wind speeds. In conditions more than 77 degrees, the water used to hydrate and cure cement can evaporate. This can lead to problems like weakness, shrinkage, and cracking.
Conclusion about concrete temperature test:
Concrete temperature testing is necessary, especially in hot or cold weather. Without this testing, your concrete might not cure the way it was intended. This can lead to weaker concrete, unnecessary cracks, and potential danger. Consulting with a structural engineer whenever using concrete is so extremely important to avoid longterm issues. It will also ensure that your investment towards your home or building is well-placed and avoid any hiccups.
