ABSTRAKT

The intrusion-extrusion hysteresis phenomenon is commonly observed during mercury porosimetry analysis. A change in contact angle between intrusion and extrusion processes, and the effect of ink-bottle pores, are generally considered as the two main mechanisms of hysteresis. This work is to further investigate the hysteresis phenomenon for different building materials (concrete and red brick) and natural rocks (shales, dolomite, tuff, and white chalk) using an approach of multicycle mercury intrusion porosimetry. Different correction methods, including the modified Kloubek method with variable constant and contact angle correction method, are used to account for the hysteresis phenomenon for different types of porous media. For all shale samples with quite a number of nanosized pores (> 60% for pore-throats < 100 nm), our results show that they exhibit more complicated hysteresis than other porous media used in this study, and the modified Kloubek method considering both variable contact angle and surface tension exhibits a better correction than the contact angle correction method. Although for other porous media tested here, the contact angle correction method could obtain an equivalent effect to the modified Kloubek method. In summary, multicycle mercury intrusion porosimetry could help elucidate the effect of ink-bottle pores for pore size distribution analysis and evaluate the effect of contact angle changes on the hysteresis phenomenon.
