“…In addition to this, it can be fully recycled based on proper technologies (Selonen et al 2000;Rana et al 2016). Physical, mineralogical and mechanical rock properties constitute a solid basis on the durability and initial use of dimension stones (Frascá and Yamamoto 2006;Figueiredo et al 2010; Mustafa et al 2015;Scrivano et al 2018). In this context, Přikryl (2013) and Salvini et al (2023) summarized several quantitative methods to investigate the durability of dimension stones (Table 1).…”

In this study, Fuzzy Inference System (FIS) was adopted to evaluate the dimension stone quality. For this purpose, 19 different rock types from different parts of Turkey were considered. Several membership functions were established using various rock properties such as dry density (ρd), water absorption by weight (wa), uniaxial compressive strength (UCS), flexural strength (FS) and Böhme abrasion value (BAV). Based on 33 if–then rules, the implementation and verification of the proposed FIS model were made in this study. The results obtained from the FIS analyses were declared as a dimension stone field performance coefficient (DSFPC), where higher DSFPC values indicate dimension stones with higher quality. The results obtained from the FIS analyses are almost in good agreement with those obtained from the field performances of the investigated rocks. However, the number of cases should be increased to improve the proposed FIS model. In this context, the number of if–then rules and membership functions can be rearranged according to the need. This study, in this manner, can be declared a case study indicating how to quantity dimension stone quality based on FIS analyses.

“…Among natural stones, granites are a major construction material all over the world and an important economic resource not only for cladding but with several other uses [21]. This type of stone is not only one of the most abundant on the earth, but also one of the hardest and most durable, hence widely used for construction [22,23]. When selected for being used as cladding material, granites are chosen due to the fact they are seen as very durable, uniform, sound, weatherresistant, low porosity materials with huge aesthetical options [24].…”

The present work sets out a finite element model for contact analysis of two different dowel fixing conditions for granite cladding. To be used in building facades as cladding materials and ornamental stones, Portuguese granites Cinzento de Alpalhão (SPI) and Amarelo de Vila Real (AVR) are considered with dowel-hole anchorage systems. FEM for contact analysis was developed (with ANSYS software) for two different dowel fixing conditions: one with regular plastic cap and the other with a fast curing mortar. Differences on strain fields between both granites with the different dowel fixing conditions were studied. Contact analysis for SPI and AVR materials show that the different dowel fixing conditions originate different strain fields. FEM results explain how different contact conditions influence the overall system stiffness (stone panel – fixing element – dowel) obtained in the dowel-hole anchorage strength tests for both granites.
