Abstract
Testing process and apparatus for determining absorption properties of a porous specimen. The porous specimen is brought in a predetermined state of contact with the body of water held by a reservoir, for inducing water absorption in the porous specimen. A weight of the porous specimen is monitored for a predetermined time period once the contact is established to produce weight data over time. The predetermined state of contact is maintained substantially constant during the time period by permanent circulation of water in the reservoir. The absorption properties of the porous specimen are determined as a function of the weight data over time.
