The best time of day to pour concrete is typically in the early morning, shortly after sunrise, or in the late afternoon, close to sunset. The reason for this is that during these times, the temperature is generally cooler, and the humidity is higher, which helps to slow down the evaporation rate of moisture from the concrete.
Concrete is a mixture of water, cement, and aggregates. When it is poured, the moisture inside the concrete mixture begins to evaporate, and if the concrete dries too quickly, it can crack and become weak. Pouring concrete during cooler temperatures and higher humidity helps to slow down the evaporation rate, which allows the concrete to cure and harden properly, resulting in a stronger and more durable final product.
In contrast, pouring concrete during hot, dry weather conditions can cause the moisture to evaporate too quickly, leading to cracking and weakened concrete. Similarly, pouring concrete during extremely cold temperatures can cause the water inside the mixture to freeze, resulting in concrete that is prone to cracking and breaking.
Overall, choosing the right time of day to pour concrete is essential for ensuring that the concrete cures and hardens correctly, resulting in a strong and durable finished product.
