How is temperature controlled in mass concrete for ...

Typically, for every 1 f 0.6 c reduction or increase in the initial concrete temperature, the maximum concrete temperature is changed by approximately 1 f 0.6 c. as an example, to reduce the maximum concrete temperature by approximately 10 f 6 c, the concrete temperature at the time of placement should generally be reduced by 10 f 6 c.
