Query: Physical-mechanical characterization of hydraulic and non-hydraulic lime
  based mortars for a French porous limestone   The focus of the study presented in this paper is to provide reliable
criteria that can be used to estimate the degree of compatibility between the
French limestone tuffeau and mortar. It is suggested through this study to use
the same parent material (i.e., tuffeau) as mortar. The mortar used in this
study is composed of non-hydraulic (hydrated) lime or hydraulic lime and
aggregates obtained from fragments and powder of the tuffeau stone. Water
transfer properties and mechanical behaviour of the mortars are evaluated and
compared with the original stone Tuffeau. Based on these studies, some key
guidelines are provided such that a mortar that is compatible with properties
of Tuffeau and can be prepared and used as construction material of monuments
and maintenance purposes.
