Influence of carbonation on the load dependent deformation of hydraulic lime mortars

▶ Lime mortar deformation attributed to creep and shrinkage mechanism. ▶ Deformation within lime matrix rather than the sand aggregate. ▶ Creep attributed to dissolution and precipitation of crystals in matrix. ▶ Creep most significant during the first fourteen days after loading. ▶ Deformation rate was a function of the extent of carbonation.
