Hydration of cement is a function of time and temperature. In absence of favorable temperature, the process of hydration slows down, thus concrete will not gain the desired strength.
Cold weather for concrete is usually defined as three or more consecutive days at which the average of temperature falls below 4°C.
Design, placement, and curing of concrete in a cold weather condition demands certain requirements. Without addressing these requirements, the quality of concrete cast in cold weather could be compromised for several reasons, including but not limited to:
- Decreased compressive strength due to lower rate of hydration
- Freezing and thawing cracks due to insufficient early strength
- Cracks due to temperature differential
GREEN-STONE™ Concrete has a number of proprietary mix designs and concrete development techniques that help clients to overcome challenges resulted from cold weather condition.
