"The properties of building materials are greatly influenced when saturated." What does this statement imply?
"The properties" refers to various characteristics and behaviors influenced by moisture
"Voids ratio represents the ratio between size of voids to volume of solid material." How does this concept affect material characteristics?
It shows how much space is available for water retention.
