“…The numerical model was created by using a commercial software, ATENA [43]. This program uses the finite element method and has nonlinear constitutive material models implemented, especially aimed for cohesive materials [13,44]. The geometry of the model is formed by the mortar specimen itself and two metallic plates as used in the experimental test (see Figure 4).…”

“…Under the hypothesis that the compressive strength of cylinder is closer to the intrinsic compressive strength of the material, we adopted their corresponding values as f c , instead of the corresponding to prisms. The metallic plates were defined as perfect linear elastic as their only function was to transmit the load and their strength was much higher than the one of the mortar [13].…”

“…In Figure 5, the square of the nominal strength of the three models for each mortar, σ N 2 , is plotted against the inverse of Hillerborg's brittleness number, 1/β H or l ch /D. By adjusting a linear fitting of these three points, it is possible to obtain the asymptotic value of the compressive strength when the specimen depth, D, tends to infinite, that is to say, the intrinsic compressive strength of the material, σ inf [13,45]. This fitted line is defined in Eq.…”

“…In general, NHL mortars are well investigated in terms of compressive and flexural strengths [5,[9][10][11]. Recently, Garijo, Zhang, and Ruiz et al [12,13] have measured fracture energy, splitting tensile strength and characteristic length of such materials. At present time, the dynamic mechanical behavior of lime mortars is getting more attention due to the fact that most masonry structures are situated in zones of seismic activity, such as Lisbon (Portugal), L'Aquila (Italy), Lorca (Spain), Kathmandu (Nepal), Nairobi (Kenya), etc.…”

Natural hydraulic lime (NHL) mortars are widely used for restoration works due to their good compatibility with the substrate material in terms of physical, chemical, and mechanical properties. Regarding their mechanical characterization, there is still a need for further understanding of their fracture behavior and the influence of their dosage methodology on the mechanical properties. Thus, this chapter focuses on the mechanical characterization of NHL mortars, such as flexural, compressive, and splitting tensile strengths, elastic modulus, and fracture energy. Moreover, the influence of the composition and production process on such properties was studied as well. Furthermore, the loading rate effect on the fracture behavior was also presented. The results show that NHL mortars have shape and size effect on the compressive strength. In addition, NHL mortar is rate sensitive, mainly due to the viscous effects caused by the presence of free water in the porous structure.

Natural Hydraulic Lime (NHL) mortars are well-extended in restoration works presently. However, there is still a lack of standardization on their dosage methodology. Thus, seven types of mortar were fabricated and five factors which have an influence on their properties have been studied, in particular the water-binder ratio, the mold material, the aggregate size and type and the different curing conditions. Furthermore, an advanced mechanical characterization has been performed on these mortars, including the measurement of the fracture energy. Finally, some empirical equations for determining the relationships between these mechanical properties were proposed, which could be helpful when simulating the numerical models of historical constructions.
