The soaked condition simulates the attack of complex overly wet weather or
rainy weather, where large amounts of water filters into the specimens. After a
desired curing (28 days ± 10 h), the specimens were immersed in deionized water
for 48 h in a room at the constant temperature of 22 ± 2 C. The water absorption
was tested after 1, 2, 3, 8, 24 and 48 h of soaked time [19]. To evaluate the water
resistance of soil-based foamed concrete, the ratio (RCS) of compressive strength
under soaked condition (CSS) and unsoaked condition (CSU) is obtained taking into
account the following expression:
