Compressive Strength Of M Concrete

Where M is the maturity at age t 176C day, T c is the average temperature of concrete during the time interval 176C, T r is the datum temperature 176C, t is an age, and t is the time interval day.. However, it is widely recognized that Sauls model underestimates the early age strength and overestimates the strength in later age 6 N.J. Carino, and R.C.
