Webbcuring concrete in extreme ambient temperatures The setting of concrete is essentially a chemical reaction, and as in many chemical reactions, the rate of cure is temperature dependent. If the ambient temperature is too low, the development of strength will slow or even stop as it nears 0°C. Webb18 okt. 2024 · Curing is the protection of concrete to prevent water evaporation and to protect it from wind, direct sunlight, frost and high temperatures. The length of time over which curing should take place is usually laid down in the concrete specification and is dependent on ambient temperatures. In simple terms, water encased in concrete is, in …
