ABSTRACT Flue-gas desulfurization (FGD) gypsum has occasionally been used as an additive to cement. Consequently, appropriate facilities are required to ensure the environmentally safe processing of FGD gypsum and the resulting cement material properties. Such facilities are yet to be developed because the amount of FGD gypsum used is still small when compared with the vast amounts of FGD gypsum generated. In this study, we analyze the effect of FGD gypsum addition on the physical properties, stabilization, and radon count of steam-cured mortar and compare its performance with air-cured mortar. Our results show that the steam-cured pozzolanic hydration products of ettringite and C-S-H promote the densification of the mortar structure, thereby resulting in nanopore size reduction and increased strength of FGD gypsum mortar subsequent to the steam-cured hydration process. Further, our environmental test results indicate that steam-cured pozzolanic materials composed of FGD gypsum are environmentally safer than air-cured cementitious materials.

Abstract TYPE 317L, 317LX, and 317LXN are austenitic alloys with varying molybdenum and nitrogen contents and thus have varying levels of resistance to pitting corrosion. All are low carbon to resist sensitization. All three alloys are intended for severe service conditions such as flue gas desulfurization systems. This datasheet provides information on composition, physical properties, hardness, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, and joining. Filing Code: SS-542. Producer or source: Allegheny Ludlum Corporation.

Abstract URANUS 52N is a nitrogen-alloyed duplex stainless steel improved in stress-corrosion cracking resistance and with pitting and crevice corrosion resistance better than AISI Type 317L. Applications include handling phosphoric acid contaminated with chlorides and in flue gas desulfurization scrubbers. This datasheet provides information on composition, physical properties, and tensile properties. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, and joining. Filing Code: SS-566. Producer or source: Creusot-Marrel.

Abstract AL 4565 alloy has a high level of austenitizers, which provides the microstructure with a high resistance to sigma formation during welding. The high nitrogen also gives the alloy superior strength among the austenitics. Applications include flue gas desulfurization and handling seawater. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness. It also includes information on high temperature performance and corrosion resistance as well as heat treating and joining. Filing Code: SS-906. Producer or source: Allegheny Ludlum Corporation.
