The fundamental behavior of sodium sulfate crystallization and induced decay in concrete and other building materials is still poorly understood, resulting in some misinterpretation and controversy.
The redox behavior of vanadyl sulfate has been studied by using glassy carbon electrode, Ag/AgCl as a reference electrode and Pt wire as a counter electrode under potential from +1500 mV to −1000 mV.
The cyclic voltammetry technique was used to study the electrochemical behavior of vanadyl sulfate in absence and presence of antibiotic (cefazolin) in 0.1 M KCl under different pH values at 300.15 K.
As these are pure single-phase standards, they are not directly Mars relevant, but studying their decomposition augments our analysis of the natural jarosite clay decomposition and our interpretation of the relative behavior of different sulfate species on Mars.
Yet even if the behavior of sulfate particles can be understood and managed, it's far from clear how injecting them into the stratosphere would affect vast, complex climate systems.
Although ignoring the heterogeneities of the system can lead to adequate prediction of the average behavior of sulfate-reducing related products, it can also lead to an overestimation of the overall accumulation of iron-reducing bacteria, as well as the rate and extent of iron reduction.
The sulfate corrosion behavior of slag cement mortar, sulfate resistance mortar and Portland mortar were investigated by means of XRD, XRF, SEM and compression test method.
This research experimentally investigated the self-healing behavior of ECC under aggressive sulfate and chloride conditions.
The effects of the type of mineral addition on the behavior of SCCs in sodium sulfate environments were studied.
Therefore, available data on the behavior of conventional concrete under sulfate attack may not be applicable to TSC.
