Abstract Buried in depth for decades of years, granite in the deep geological repository will be subjected to extremely complex effects of thermo-hydro-mechanical (THM) treatment, and the tensile strengths of mineral grain interfaces (MGIs) are inevitably impacted by the THM treatment [1, 2]. Originated by the failure modes of granite after THM treatment, the tensile strength of MGI plays an important role in determining the macro mechanical properties of THM-treated granite [3, 4]. However, the accurate characterization of the tensile strength degradations of MGIs with THM treatment is still lacking. In this study, the varied tensile… More >

Abstract In general, acid aggregates are not used in combination with asphalt concrete because of their poor compatibility with the asphalt binder, which typically results in a scarce water stability of the concrete. In the present study, the feasibility of a new approach based on the combination of acid granite fine aggregate with alkaline limestone coarse aggregate and Portland cement filler has been assessed. The mineral and chemical compositions of these three materials have first been analyzed and compared. Then, the effect of different amounts of Portland cement (0%, 25%, 50%, 75% and 100% of the… More >

Abstract Granite is generally composed of quartz, biotite, feldspar, and cracks. The changes in digital parameters of these compositions reflect the detail of the deformation process of the rock. Therefore, the estimation of the changes in digital parameters of the compositions is much helpful to understand the deformation and failure stages of the rock. In the current study, after dividing the frames in the video images photographed during the axial compression test into four parts (or, the upper left, upper right, lower left, and lower right ones), the digital parameters of various compositions in each part… More >

Abstract Granite stone is a by-product of the rock crushing manufacturing. An industrial waste in powder form that causes health problems and environmental pollution. Fine particles fraction can be used as a partial replacement of sand in concrete manufacture. In this work, an alternative exploitation of this waste fraction is proposed. Granite sand (GS) with particles mean size of ~1 μm was employed as thermoplastic starch (TPS) filler at different concentrations. Biocomposites were obtained by melt-mixing and thermo-compression, achieving translucent and easy to handle films. A good GS dispersion within the matrix was evidenced by SEM. More >

Abstract The mechanical behaviors and energy dissipation characteristics of heat-treated granite were investigated under repeated impact loading. The granite samples were firstly heat-treated at the temperature of 20°C, 200°C, 400°C, and 600°C, respectively. The thermal damage characteristics of these samples were then observed and measured before impact tests. Dynamic impact compression tests finally were carried out using a modified split-Hopkinson pressure bar under three impact velocities of 12 m/s, 15 m/s, and 18 m/s. These test results show that the mineral composition and the main oxides of the granite do not change with these treatment temperatures.… More >
