“…The chemical process is described in the literature (Stanton 1940;Swamy 1992;Brivot 1992, 1993;Fournier and Bérubé 2000), and in addition to the physical and chemical tests, the petrographic examination of aggregates is a basic method to predict the potential reactivity (e.g. West 1994;Ramachandran and Beaudoin 2000;Ahmad et al 2018;Šachlová et al 2016, 2017. In the Hungarian Danube sediments, being silicate-based lithological assemblages, ASR-sensitive forms of silica (micro-or cryptocrystalline quartz, submicroscopic or disordered quartz, strained quartz, opal, chalcedony, tridymite, cristobalite, devitrified glass) are determined and quantified, since those can be harmful in the concrete mixture already in small amounts (e.g.…”

“…Prediction of chemical stability of aggregates in concrete is preferentially done by detailed petrographic examination (e.g. West 1994;Ramachandran and Beaudoin 2000;Šachlová et al 2016, 2017Kuchařová et al 2016;Ahmad et al 2018) or by wellestablished physical tests (e.g. ASTM C 1260 2014, RILEM AAR-1,-2 2016).…”

This paper evaluates the applicability of Hungarian oligomictic alluvial gravel formations at two sections of the Danube river for construction use. The classification of these aggregates is more challenging than monomictic rock aggregates due to their heterogeneous nature. Multi-source clastic sediments cannot be characterized by single values of physical properties but only a distribution, and they are generally less predictable than monomictic materials. The possible applications in concrete manufacturing were evaluated by complex macro-microscopic petrographic, heavy mineral and nuclear analytical geochemical investigations. The two regions falling on the middle course of the Danube have similar sandy gravel formations, applicable as aggregates for conventional and unconventional concrete building purposes or road construction. Their utilization in open-air constructions might be problematic due to their probable alkali-silica reactivity.

“…An accelerated test method such as ASTMC 1260 is one of the methods applied to evaluate the reactivity of the aggregate to ASR [4,24]. In addition, the observation of microstructure with scanning electron microscope with SEM/EDX and elemental changes in concrete specimens are the methods used to understand ASR [20,25,26].…”

Basaltic rocks are the main source of local crushed rock aggregate for concrete in their region. Basaltic rocks are also potential rocks for alkali–silica reaction (ASR). ASR is a complex mechanism that deteriorates concrete via creating volumetric expansion over time between the reactive silica in the aggregate and the alkali components in Portland cement. However, due to the multi-scale nature of this long-term phenomenon, understanding its mechanism in concrete structures remains difficult to assess. In this study, the morphology and analytical composition of three groups of concrete prepared with basalt aggregate, basalt aggregate with 20% fly ash substitution of cement, and limestone aggregate were analyzed using scanning electron microscopy (SEM) and energy-dispersive X-ray spectrometry (EDX); it was characterized using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), and differential thermal analysis (DTA) and compared with the ASR structure. The (Na + K)/Si and Ca/Si ratios in SEM/EDX analysis and the water peaks in FT-IR and TGA analyses will help to determine the footprint of ASR.
