  • Modeling of Hydration, Compressive Strength, and Carbonation .

     · Regarding compressive strength, the use of limestone in concrete with low watertobinder ratios is a more rational option. Third, the calculation results from the hydration model, such as carbonatable material contents and porosity of concrete, are used as input parameters for the carbonation model. CO 2 diffusivity and carbonation depth of PLC concrete are evaluated .
