dc.description.abstract© 2014 CSIC. This paper compares different experimental methods for measuring water permeability in 17 different porous building rocks. Both commercial apparatus and specially made designed permeameters are used for characterising intrinsic permeability and hydraulic conductivity, k, of rocks in the range of 10-12 to 10-4 m/s (∼ 10-19-10-11 m2 or ∼ 10-4-104 mD). We use both falling head and constant head permeameter methods including the triaxial and modified triaxial tests and a classical constant head permeameter. Results showed that for very low and low permeability samples (k<10-6 m/s), triaxial conditions were found the most accurate procedures and they provided similar or slightly lower permeability values than constant and falling head methods. The latter techniques were highly recommended for permeable and high permeable porous building materials. Water permeability values were also linked to effective porosity and interpreted in terms of interparticle and vugs porosity. Finally, some modifications in the apparatus and procedures were carried out in order to assess water permeability in soft materials, which involve the use of non-saturated samples.-
dc.description.abstract[EN] This paper compares different experimental methods for measuring water permeability in 17 different porous building rocks. Both commercial apparatus and specially made designed permeameters are used for characterising intrinsic permeability and hydraulic conductivity, k, of rocks in the range of 10−12 to 10−4 m/s (~ 10−19−10−11 m2 or ~ 10−4−104 mD). We use both falling head and constant head permeameter methods including the triaxial and modified triaxial tests and a classical constant head permeameter. Results showed that for very low and low permeability samples (k<10−6 m/s), triaxial conditions were found the most accurate procedures and they provided similar or slightly lower permeability values than constant and falling head methods. The latter techniques were highly recommended for permeable and high permeable porous building materials. Water permeability values were also linked to effective porosity and interpreted in terms of interparticle and vugs porosity. Finally, some modifications in the apparatus and procedures were carried out in order to assess water permeability in soft materials, which involve the use of non-saturated samples.-
dc.description.abstract[ES] Comparación de métodos experimentales para medir la permeabilidad al agua en rocas de construcción porosas. Se comparan diferentes métodos experimentales para la medida de la permeabilidad al agua en rocas porosas usadas como material de construcción. Se usaron diferentes permeabilímetros, (comerciales y desarrollados específicamente) empleando los métodos triaxial, triaxial modificado, carga constante y carga variable. Se caracterizó la permeabilidad intrínseca y conductividad hidráulica, k, con valores que varían desde 10−12 a 10−4 m/s (~ 10−19–10−11 m2 or ~10−4–104 mD). Para muestras poco y muy poco permeables el ensayo con célula triaxial fue el mas reproducible. Los ensayos de carga constante son muy recomendables para rocas porosas de construcción permeables y muy permeables. Además, se definen los parámetros experimentales más apropiados para caracterizar la permeabilidad de rocas de construcción. La permeabilidad al agua se relaciona con la porosidad efectiva y se interpreta en términos de porosidad tipo interpartícula y vugs. Finalmente, se modificaron los equipos y procedimientos para poder estimar la permeabilidad en materiales blandos.-
