Temperature effects_maturity
In the CEB-FIP Model Code 90 , maturity is a concept used to predict the rate at which concrete gains strength based on temperature and time. Eq. (2.1-87) is used to calculate the maturity-adjusted time $$ t_T$ $ , which accounts for the effects of temperature on concrete's strength development. \( S=\int d^{4} x\left(\frac{R}{2 \kappa}\right) \) begin{eqation} S=\int d^{4} x\left(\frac{R}{2 \kappa}\right) end{equation} Definition of Equation (2.1-87): The maturity-adjusted time $$tTt_T tT$$ is calculated as: $$tT=∫t0texp[QR(1T0−1T(τ))]dτt_T = \int_{t_0}^{t} \exp \left[ \frac{Q}{R} \left( \frac{1}{T_0} - \frac{1}{T(\tau)} \right) \right] d\tau tT=∫t0texp[RQ(T01−T(τ)1)]dτ$$ Where: tTt_T tT = maturity-adjusted time (in days) tt t = real elapsed time (in days) t0t_0 t0 = start time for the calculation (usually 0) QQ Q = activation energy for hydration process, typically around 33,500 J/mo...
