Concrete typically sets within three hours and is generally cured to full strength within 28 days. However, drying times can vary depending on external weather conditions and the type of concrete utilized in the project. Concrete dries at an accelerated rate within the first seven days of placement.
Concrete placement during hot weather conditions can lead to a drop in moisture levels which in turn can cause cracks to develop. Lack of moisture can also prevent concrete from drying to full strength, so it is important to pour the concrete during early morning hours to minimize heat impact. Extremely cold weather conditions can hinder the curing process and minimize the overall strength of the concrete. Placing tarps and blankets over the concrete during colder conditions can help to prevent damage..
