WebPorosity or void fraction is a measure of the void (i.e. "empty") spaces in a material, and is a fraction of the volume of voids over the total volume, between 0 and 1, or as a percentage between 0% and 100%. Strictly speaking, some tests measure the "accessible void", the total amount of void space accessible from the surface (cf. closed-cell foam).. There are … WebMar 6, 2024 · The nuclear magnetic resonance (NMR), ultrasonic testing, and triaxial compression tests were employed to investigate the deterioration laws of multiple physical and mechanical properties of sandstone under different pore water pressure cycles, and Micro- and Meso- deterioration mechanisms were analyzed via scanning electron … WebMay 1, 2005 · The average results of the compression test are given in Table 4. The average results of the porosity test are presented in Fig. 2, Fig. 3. It is revealed from the test results that the water–cement ratio and curing age significantly influenced the strength and permeable porosity of concrete. The permeable porosity of NPCC50 at.
