        <dc:description>Earth-based mortars have been used all over the world since ancient times in an extensive range&#13;
of building types from vernacular architecture to monuments. Plastering is one of the most&#13;
common contemporary applications of earth-based mortars used for earthen-building conservation&#13;
or modern architecture. Raw earth is a very diverse natural material, and clay minerals play&#13;
a key role in plaster properties being responsible for their setting process and providing the&#13;
capacity of balancing the indoor hygrometric conditions of buildings. This capacity offers significant&#13;
benefits to energy savings delivering comfort and health of inhabitants and also contributes&#13;
to building conservation. For this study, three mortars were produced with different&#13;
clayish earths to assess the influence of clay mineralogy. Mortars characterization confirmed that&#13;
clay mineralogy drives important plaster properties, such as vapour adsorption and drying&#13;
shrinkage, while also having a significant influence on mechanical strength, dry abrasion, and&#13;
thermal conductivity. Within the studied mortars, illitic clayish earth stands outs as more adequate&#13;
for earth-based plasters, showing balanced properties, namely linear drying shrinkage, mechanical&#13;
strength, dry abrasion, and water vapour adsorption.</dc:description>
