Maturity of Prestressed Self-Consolidating Concrete
The maturity method applies the fundamental concept that concrete strength develops with time as the cement hydrates and releases heat. The rate of strength development at early ages is related to the rate of hydration of cement. In this investigation, 27 Self-consolidating concrete (SCC) mixtures made with various mixture proportioning parameters, including maximum size and type of aggregate, type and content of binder, and w/cm were evaluated. Based on this investigation, SCC proportioned with 0.33 w/cm exhibited lower maturity at the same strength level compared to that with 0.38 w/cm; and for the same 0.38 w/cm, SCC made with Type MS cement had higher maturity compared to those proportioned with Type HE + 20%FA and Type HE + 30%S, at the same strength level.
