Implication of pore size distribution parameters on compressive strength, permeability and hydraulic diffusivity of concrete

In this study, compressive strength, permeability and hydraulic diffusivity of three different grades of concrete have been estimated through pore size distribution (PSD) parameters by using mercury intrusion porosimetry (MIP). For this purpose, cubical concrete specimens are crushed and the broken...

From the cumulative intruded volume versus pressure data obtained from MIP experimentation, the experimental pore size distribution parameters such as mean distribution radius (r0.5), dispersion coefficient (d) and permeable porosity (P) are calculated. The estimated PSD parameters are used to estimate the compressive strength, permeability and hydraulic diffusivity through the readily available relationships for compressive strength, permeability and hydraulic diffusivity.
