Dec 19, 2018· When hotweather concreting, a general rule of thumb is to maintain a limit of 70°C (160°F) for concrete curing temperature during hydration. If the temperature of the concrete during hydration is too high, the concrete will gain strength faster early on but consequently, lose strength in later stages and thus be less durable.
