8 Σεπ 2023 · After calcium chloride replaced calcium sulfate, the compressive strength was improved. At a Ca 2+ (CaCl2)-Ca 2+ (CaSO4) ratio of 1:1, the strength was increased by 44% and 18% at 3 days and 28 days, respectively, compared with the addition of calcium sulfate alone.
30 Ιουν 2021 · The early presence of sulfate ions in a saturated calcium hydroxide solution was shown to affect the corrosion behavior of the steel. The higher sulfate ion concentrations resulted in the increase of the anodic current exchange density.
1 Ιουν 2022 · The behavior of galvanized steel exposed to strong alkaline solutions (pH values of 12.7) with a fixed concentration of sulfate ions of 0.04 M is studied here.
1 Μαρ 2016 · The corrosion characteristics of reinforced steel in simulated concrete pore solutions with different amount of chloride ion and sulfate ion were investigated by means of polarization curves...
1 Οκτ 2010 · The role of sulfate (SO42-) ions on pitting corrosion of Stainless Steel-316 (SS-316) and inhibition mechanisms of meta-silicate ions (SiO32-) above critical pitting temperature (CPT) were ...
21 Μαρ 2024 · In solutions containing SO 42− and HCO 3− in anaerobic environment, a high proportion of HCO 3− /SO 42− leads to the passivation of Q345 carbon steel sample as a result of the competitive adsorption of HCO 3− on substrate surface with smaller radius.
7 Σεπ 2015 · The results showed that T23 and T12 were susceptible to pitting corrosion in the simulated solution with full SO 4 2− concentration for the competitive adsorption of OH− and SO 4 2− on the surface of steels. The pitting sensitivity of the steels improved with increasing SO 4 2− concentration.
