الملخص EN
Water and gas permeability coefficients of concrete with different water-binder (w/b) ratios and admixtures were measured by a self-designed test device based on the steady-state flow method for liquid and the method of differential pressure in stability for gas, respectively.
In addition, the micropore structure of concrete was determined by 1H nuclear magnetic resonance (NMR).
Results indicated that there are good correlations between water and gas permeability of concrete with different w/b ratios, with correlation coefficient greater than 0.90.
Better correlations between water permeability and segmental contributive porosity ranged from 10 to 100 nm and 100 to 1000 nm can be identified, but the gas permeability is more relevant to the segmental contributive porosity ranging from 100 to 1000 nm.
Moreover, the correlation between water permeability and contributive porosity for each pore diameter is always better than that of gas permeability.
The influence of admixtures on the relationship between permeability and pore size distribution of concrete is significant.
Moreover, water permeability coefficient is one or two orders of magnitude lower than the gas permeability coefficient.
