Due to their excellent water tightness and strength, cementitious materials are used to build WWTPs. However, the performance of these materials is affected by aggressive environments. There are few in situ experiments in the literature regarding the deterioration of cementitious materials in WWTPs. This paper investigates their deterioration mechanisms in a sewage pumping station and a sand-trap structure of a WWTP. In situ experiment was conducted by exposing cement specimens in both locations for 1, 2, 3 and 7 months. The physical and morphological changes of the specimens were examined using stereo microscopy and scanning electron microscopy, whereas the mineralogical/solid phase changes were examined using X-ray diffraction. The results showed that the specimens from the pumping station formed colored surface products, which were confirmed to be secondary minerals (i.e., gypsum and ettringite), whereas there were no colored surface products in the sand-trap structure. The results demonstrated that cementitious materials subjected to wastewater vapors (in a pumping station) had higher deterioration effects than those subjected to wastewater liquid (in a sand-trap structure), suggesting that the wastewater vapors are more aggressive toward cementitious materials than wastewater liquids.

The BFVA is a deeply eroded and dissected volcanic field dominated by multiple, several 10-m thick, valley-filling silicic ignimbrite units, which are chemically and texturally very similar to each other. Hence, establishing lateral correlation is a real challenge due to the sporadic and small-scale outcrops and lack of stratotypes. Detailed field observations allowed us to identify eleven lithological members including fourteen eruption events and establish a nearly complete lithostratigraphic correlation between fifteen outcrops across the BFVA. Primary pyroclastic material of each member was sampled, and volcanic glass was analyzed for major and trace element composition. The geochemical results confirm the field-based classification of the members and enable the correlation of distinct outcrops. The major and trace element composition of the glassy pyroclasts of each member of the BFVA served as basis to create a field-wide chemical reference database for regional correlational studies. Here, a new lithostratigraphic classification scheme consisting of one formation and eleven members is presented, which reflects the challenges unraveling the stratigraphy of ancient volcanic terrains. The field-based event-scale lithostratigraphy of the BFVA suggests a wet, partly sea-covered depositional environment in the close vicinity of the eruption centers providing favorable conditions to ‘fuel’ silicic explosive phreatomagmatism. On the contrary, paleosol horizons formed after almost each major eruption event or sequence suggests an overall near-coast terrestrial environment for the BFVA, where the emplacement of the pyroclastic material occurred.

Examination of the surface patterns of volcanoes might help us understand better the process of magma generation, segregation, and how magma travelled through a thin lithosphere. Moreover, by studying these processes, we can get closer to understanding the evolution of a sedimentary basin in which we can find the link between volcanism and a changing but essentially compressive stress field, where basaltic volcanism is not evident. These spatial patterns of volcanoes can be examined using GIS (geographic information systems). The study area was the Mio-Pleistocene, monogenetic Bakony-Balaton Highland Volcanic Field (BBHVF, Carpathian-Pannonian region, Central Europe), which is located in continental back-arc setting and compressive/transpressive tectonic regime. The methodological toolkit included creating heatmap based on the spatial distribution of the volcanoes, measuring the orientation of the volcanic field comparing the orientation of the faults in the region, and calculating distance to the nearest fault line from each volcanic centre. Poisson nearest neighbour analysis was used to evaluate how clustered or random the occurrence of the volcanoes across the volcanic field. All volcanic lineaments (whether volcanic centres are situated along lines) were calculated, and their orientation was measured to see any systematic directions. The results suggest that the locations of the volcanoes in the BBHVF are most probably tectonically determined. The orientation of volcanic lineaments is also the same as the bounding geometries and the faults. Density of the volcanic centre distribution is the largest in the central area of the BBHVF along a major inactive thrust fault. We speculate that the NW dipping fault plane of this fault could be a ‘catchment area’ in the upper crust (just above the brittle-ductile transition zone), which channelized the magmas and helped them reach the surface. Volcanoes in larger distance from any faults have typically larger volume, and longer active period (several 100 ky), thus their magmas needed to have larger buoyancy to reach the surface without the help of any fault planes. Age pattern and spatial density suggest volcanism getting younger and thicker towards the central part of the BBHVF. Thus, intracontinental monogenetic volcanism in compressional regime is strongly influenced by lithospheric weaknesses and the regional stress field.
