Abstract

The hardenable mortar composition consists of a bonding agent component including a hydraulic bonding agent, such as cement, gypsum or mortar, and a paste-forming agent consisting of a liquid solvent inert with respect to the hydraulic bonding agent, and an aqueous component kept separate from the bonding agent component until the two components are mixed to form a hardened mortar composition. The aqueous component includes water and a hydrophobic adsorbent or absorbent. The hydrophobic adsorbent or absorbent is included in the aqueous component to avoid the emergence of the paste-forming agent, which is at the very least unsightly, when the aqueous component is mixed with the bonding agent component. The hydrophobic adsorbent or absorbent binds the paste-forming agent which would otherwise escape during mixing and remains as an inert additive in the setting mortar composition, without reducing the hardness thereof.
