Question
You are assigned to monitor the concrete strength gain at a construction site. The ultimate compressive strength of the concrete at its full maturity is 450 kg/m. The average concrete temperature at the construction site is 25 °C during the day and 15 °C during the night (assuming 12-hour day/night cycles). If you assume that the datum temperature (To) is - 10 °C, estimate the strength of concrete after 14 days. (4=35, B=51)
Maturity Index, M = E(T - To).
