In general, lime mortars have two parts: binder and aggregate; that each part of the mortar can be effective in creating various characteristics in the mortar. The binder part is divided into two types of hydraulic and air lime, and the mortar aggregates section mostly includes silicate minerals and sometimes carbonate aggregates. The difference between hydraulic lime and air lime is in the way they are carbonated, as well as the presence of silicate, aluminate and iron-bearing minerals, which are seen in hydraulic lime as calcium silicates and calcium aluminates in the structure of the lime binder. The goals of this article are: A: A brief overview of the properties of lime mortars in order to understand the effect of aggregates and aggregates in the mortar. B: Structural analysis of mortar in order to investigate the hydraulic properties of lime mortar of the case sample of the mortar of QaraKorpi (Black bridge) structure in maku. C: Determination of the size and grading of the historical case sample. According to the obtained results, it was found that the type of lime used is non-hydraulic or air lime and the type of aggregates used is mostly quartz and the maximum size group of aggregates in the mortar sample includes clay aggregates and fine sands, which can be attributed to the destruction of the mortar in Its lifespan or some kind of structural weakness during mortar construction. To achieve the goals of this research, FTIR, XRD, XRF and soil granulation machine were used.
