WebIt is possible for concrete to freeze shortly after it is poured, depending on the environmental conditions. Generally, concrete needs around 24 to 48 hours to reach a point of minimal freezing risk. However, when temperature drops below 0°C (32°F) and moisture is present, the risk of concrete freezing increases dramatically. WebCuring Times for Concrete Typical industrial concrete will recognise its full workable strength at the 28 day mark. After 7 days of curing, the concrete will have reached approximately 70% strength. For those who are laying concrete in a domestic area, like the garden, concrete is reasonably set within 24-48 hours.
WebTherefore, protective blankets should be removed as soon as possible after 48 hours but no longer than 72 hours. Can you pour concrete if it freezes at night?
