The concrete containing Type I cement in a structure is cured for 2 days at 68°F, followed by 2 days at 42°F. Use the maturity concept to estimate its strength as a percentage of the 28-day strength under standard curing. Maturity is defined as M = Σ(Ti + 50)(ti) where Ti is in degrees F and ti is in days.
