Influence of Temperature on Sulfate Attack of Limestone Filler Cement Mortar高小建摘 要:<正>Mortar prisms were made with three different cementitious materials (with or without mineral admixture) plus 30% mass of limestone filler. After 28 days of curing in water at room temperature, the mortars were submerged in 2% magnesium sulfate solution......
Long-term Behavior of Fiber Reinforced Concrete Exposed to Sulfate Solution Cycling in Drying-immersion耿永娟1,金祖权1,HOU Baorong2,ZHAO Tiejun1,GAO Song11. School of Civil Engineering, Qingdao... to 60 and 170 drying-immersion cycles of sulfate solution, were systematically investigated. The effects of plain concrete, plain concrete mixed with 4 and 8 kg/m3 modified PP fiber and high......

Hot Corrosion Behaviors of Ni-14%Cr Alloys in Molten Sulfate () 摘要:The corrosion behaviors and mechanism of Ni-14%Cr alloys in molten salt with Na_2SO_4 at 1000℃ was investigated by means of XRD analysis and SEM observation. Results show that the alloys were subjected to the accelerated corrosion in molten salt and the corrosion kinetic of the alloy obeys the parabolic law. On the other hand......
