How Does Temperature Affect Concrete

Concrete expands when the temperature rises and contracts when the temperature drops. Temperature is an essential consideration in all construction jobs. It has a significant impact on the finished durability of concrete.

When the Temperature is Too Hot

Concrete that is freshly poured will set quicker if the weather is hot. This is because the moisture evaporates from the concrete faster in hot weather.

Concrete is more likely to crack when poured in hot weather, causing it to dry quickly. The high temperature when pouring concrete causes the concrete to lose moisture and results in voids in the finished structure, reducing its durability.

When the Temperature is Too Cold

It is also more prone to crack if the temperature drops very quickly at night. If the temperature drops below 25 degrees Fahrenheit, the concrete will freeze, reducing its strength by over 50%. Also, concrete should never be poured when the ground beneath it is frozen.

The frozen ground will settle as it warms up, causing any concrete poured above it to be susceptible to cracks. Because temperature conditions impact the overall durability of the finished concrete, it is crucial to pay close attention to the weather.

The Ideal Temperature for Concrete

The ideal temperature for pouring concrete is between 50 and 60 degrees Fahrenheit. Additionally, it is good to pour concrete when the temperature remains moderate without any sudden rise or fall.
