What is the Best Temperature for Pouring Concrete
· The ideal temperature for pouring concrete is between 50 and 60 degrees Fahrenheit. This is because concrete gains its strength and durability through a process known as hydration which can be affected by conditions of extreme heat or cold.

Why Concrete Temperature Testing Is Important During
· Why Concrete Temperature Testing Is Important During Extreme Weather. The heat produced by concrete during curing is called heat of hydration. This exothermic reaction occurs when water and cement react. The amount of heat produced during the reaction is largely related to the composition (Table 1) and fineness of the cement.
