Measurement of the Hygric Resistance of Concrete Blocks with Perfect Contact Interface: Influence of the Contact Area

Table 5: Values of hygric resistance for the perfect contact interface samples, with different heights and contact area.

Base (cm²)	Interface Type	Hygric Resistance (kg/m²s)	Standard Deviation	Coefficient Variation (%)
5.0x5.0	Perfect contact (at 12cm)	1.66x10^-5	1.60x10^-6	9.6
5.0x5.0	Perfect contact (at 9cm)	1.68x10^-5	1.59x10^-6	9.4
7.5x7.5	Perfect contact (at 12cm)	1.65x10^-5	2.26x10^-6	13.7
7.5x7.5	Perfect contact (at 9cm)	1.41x10^-5	2.31x10^-6	16.4
10.0x10.0	Perfect contact (at 12cm)	1.77x10^-5	2.07x10^-6	11.7
10.0x10.0	Perfect contact (at 9cm)	1.62x10^-5	2.78x10^-6	17.2
