ABSTRACT
This RILEM recommendation specifies a method of determining the capacity of plastering, rendering and bricklaying mortars to retain water when in contact with an absorbent surface.
The capacity of a mortar to retain part of its water content when it is in contact with an absorbent surface, similar to that which occurs in use for bricklaying or plastering, is of importance because the properties of the hardened mortar depend largely on the retention of adequate water to complete the chemical processes of curing.
