The article presents the chemical bases of the destruction of concrete and reinforced concrete structures of bridge structures by the aggressive action of water (carbonization) and salts (corrosion). / В статье представлены химические основы разрушения бетонных и железобетонных конструкций мостовых сооружений агрессивным воздействием воды (карбониз...
The work is devoted to the study of the protective coating formed when using Mg-NTP as a corrosion inhibitor, the study of the thickness of the coating depending on the exposure time and the duration of the protective effect of the film. / Работа посвящена исследованию защитной пленки, образующейся при использовании Mg-НТФ в качестве ингибитора кор...

Le béton armé est un matériau très utilisé dans les constructions et notamment dans le génie civil. La principale pathologie du béton armé est la corrosion des armatures en acier carbone qui peut survenir lorsque les ions chlorure sont présents en teneur suffisante au niveau des armatures (ou bien lorsque le béton d'enrobage est totalement carbonat...

Le béton armé est un matériau très utilisé dans les constructions et notamment dans le génie civil. La principale pathologie du béton armé est la corroson des armatures en acier carbone. Dans ce travail, l'utilisation d'armatures en acier inoxydables en remplacement de l'acier carbone pour des milieux très fortement chlorurés est étudiée sur une pé...
Brass is a relatively stable alloy but it tends to tarnish over time due to the interaction with the atmosphere. Thus, it is rare to observe centuries-old brass objects untouched by the passing of time. For this reason, the pristine appearance of hundreds of brass sequins in the Enclosed Gardens of Meche len (reliquary altarpieces produced between ...
The dissolution behavior between CaO–SiO2–Al2O3–FexO slag and Al2O3 particles was studied by the Single Hot Thermocouple technique (SHTT) at 1550 °C. The FexO content in the slag with a fixed basicity (CaO/SiO2 ratio) of 1 varied from 10 to 30%. The dissolution behavior between slag with transition metal oxides and Al2O3 particles was investigated ...
Historic shipwrecks form an anthropogenic landmark in marine environment, yet their influence on the local geochemistry and microbiology remains largely unexplored. In this study, sediment and steel hull samples were taken around the V-1302 John Mahn, a World War II shipwreck, at increasing distance from the wreck, in different directions. Polycycl...
