Prediction of Strength, Permeability, and Hydraulic Diffusivity of Ordinary Portland Cement Paste

In this investigation, the compressive strength, permeability, and hydraulic diffusivity of ordinary portland cement (OPC) paste have been predicted from the knowledge of mixture factors, such as water-cement ratio (w/c) and curing ages. The relationships for pore size distribution (PSD) parameters, such as mean distribution radius r(0.5), dispersion coefficient d, and permeable porosity P, are functions of the w/c and curing ages, and are readily available in the literature. By using these relationships, the compressive strength, permeability, and hydraulic diffusivity can be estimated from the w/c and curing age information. It is observed that the predicted compressive strength closely matches the reported experimental compressive strength. It is also observed that the estimated permeability data also closely matches the reported experimental permeability data. The predicted hydraulic diffusivity follows a similar trend, as reported in the literature.
