Investigation of suitability of marbles to standards with inequality expressions and statistical approach using some physical and mechanical properties

Abstract

Marble, one of the metamorphic rock formation products, forms by undergoing different physical and chemical processes. The marble samples are tested under laboratory conditions to understand these processes. This study aims to find whether the Akcay region marble (Antalya) is compatible with national and international standards using some physical and mechanical properties. For this purpose, samples were subjected to some laboratory tests (real density, apparent density, total porosity, open porosity, breaking load, compressive strength, flexural strength, rupture energy). A number of statistical findings, linear equations, inequalities, and spatial distribution maps were obtained from the physical and mechanical data found at the end of the laboratory tests. The variables which were found to be statistically significantly correlated according to the results of the correlation analysis were analyzed using regression analysis; then their distributions were explained using linear equations. The spatial distribution maps of the variables reveal the part corresponding to the symbol color ranging between the light green and yellow and covering almost 70% of the area is compliant with both TurkStat and ASTM standards and this is proved using the inequalities.

Development of calcium sulfoaluminate cements from rich‐alumina bauxite and marble wastes: Physicochemical and microstructural characterization

“…2020 and Caron et al. 2010 31,33 . The sample ML and GC show calcite (CaCO 3 , ICCD 05‐586) and bassanite (CaSO 4 •0.5H 2 0, ICCD 41‐0224) as main crystalline phases, respectively.…”

“…The bauxite sample HB mainly consists of aluminum (Al 2 O 3 ) and iron (III) (Fe 2 O 3 ) oxides at 59.08 and 5.12 wt%, respectively, whereas sample bauxite LB contains silica (Si 2 O), alumina, and iron (III) oxide at 28.30, 8.81, and 46.90 wt%. This high content of alumina and the Al 2 O 3 /SiO 2 modulus ratio equal to 57.36 in the bauxite HB sample classify it as high alumina ore25,31,32 suitable for the synthesis of the sulfoaluminate cement. However, the LB sample (another bauxite poor in alumina) has a module ratio of 0.31 lower than HB.…”

Geochemistry of Red Soils in the Kas District of Antalya (Türkiye) Using Multivariate Statistical Approaches and GIS

“…The Kaiser-Meyer-Olkin test was conducted to evaluate the suitability of the data for factor analysis [63][64][65][66] (Table 7). The data were found to be suitable for factor analysis, and the sampling adequacy measure was found to be greater than 0.5 [67][68][69][70][71][72][73]. The number of factors under which the data were collected was interpreted using the scree plot (Figure 8).…”

Investigation of the Effect of Hydrothermal Waters on Radionuclide Activity Concentrations in Natural Marble with Multivariate Statistical Analysis

“…A correlation analysis was performed to reveal the relationship between radionuclides, radiological parameters, and chemical concentrations. Kolmogorov-Smirnov and Shapiro-Wilk normal tests are performed for the statistical analysis of data obtained in different ways [10,16,49]. The normality of the data was tested performing Kolmogorov-Smirnov and Shapiro-Wilk tests (Table S2).…”
