“…As can be seen from Fig. 5 sample of plain cement showed a finer pore network with maximum pore volume at 1.416 nm in microporosity range and 3.385 nm in mesoporosity range, and it is in line with the recent results obtained by others [28][29][30]. Since curves of samples with OC addition were far more flat and overlaid each other, they were enlarged to see the impact of OC type on the pore size distribution more clearly.…”

“…16 The purpose of this method was to validate the pozzolans usage and measure their effect on the microstructure of the concretes. 17 Imaging diagnostic tests also turn out to be an option for identifying distribution and quantity of pores with higher precision. The most commonly used for durability of concrete structures is the 3D microtomography, which has wide range of uses in materials science.…”

Diagnosing and understanding the properties of concrete structures allows its use in more effective ways that neither compromise application nor impose safety risks or waste materials. Several tests can be performed for this purpose, differing with regards to diagnostic precision, complexity of execution, costs, need of specific apparatus, and others. Specifications from standards must be followed to assure the durability of concrete structures, such as Eurocode 1 (EN 1992‐1) and EN 206 in Europe. This study determined the volume and the distribution of pores of four concrete compositions with distinct water/cement ratio, cement consumption, and compressive strength, through tests of mercury intrusion porosimetry (MIP) and 3D microtomography. Results showed high correlation coefficients between the tests for assessing voids and compressive strength. Comparatively, the 3D microtomography test presented linear relation to the specifications of mixtures, although MIP indicated discrepancies for mixture 2.

“…According to the Washburn equation, the seemingly complicated distribution of pore size in a coal matrix can be precisely analyzed with a mercury injection experiment (Hyv€ aluoma et al, 2004;Panesar and Francis, 2014). Some scholars even formulated a fractal relationship between the mercury pressure and pore size (Songhang et al, 2009;Yao et al, 2009)…”
