Effect of concrete placing temperature on early thermal movement
Rate of hydration of cement paste is related to placing temperature of concrete. Rate of heat production is given by empirical Rastrup function:
H=H0×2r (T-T1)
Ho = Rate of heat production at a reference temperature
T = Temperature where rate of heat production H
T1 = Temperature where rate of heat production Ho
r = 0.084
A 12o C increase in placing temperature doubles the rate of reaction of hydration. Henceforth concrete placed at a higher temperature experiences a higher rise in temperature. For example concrete placed at 32oC generates heat of hydration twice as fast when compared with concrete placing at 20oC. Therefore high concrete placing temperature has significant effect to problem of early thermal movement.
