Sulfate resistance of cementitious systems with mineral additives
Dilek, Faruk Tuncer; Tokyay, Mustafa; Department of Civil Engineering (2002)
Sulfate resistance of mortars containing limestone, trass, granulated blast furnace slag and fly ash has been evaluated using ASTM C 1012 test procedure. Prismatic and cubic mortar specimens have been stored in concentrated sodium sulfate and a mixture of sodium sulfate + magnesium sulfate solutions. Relative deterioration of the specimens has been determined by length change, weight change, strength and visual examination. From similar mixtures, cement paste specimens were prepared and structure/morphology...
Sulfate resistance of blended cements with fly ash and natural pozzolan
Duru, Kevser; Yaman, İsmail Özgür; Department of Civil Engineering (2006)
Numerous agents and mechanisms are known to affect the durability of a concrete structure during its service life. Examples include freezing and thawing, corrosion of reinforcing steel, alkali-aggregate reactions, sulfate attack, carbonation, and leaching by neutral or acidic ground waters. Among these, external sulfate attack was first identified in 1908, and led to the discovery of sulfate resistant Portland cement (SRPC). Besides SRPC, another way of coping with the problem of sulfate attack is the use o...
Sulfate resistance of plain and blended cements exposed to wetting-drying and heating-cooling environments
Sahmaran, M.; Erdem, T. K.; Yaman, İsmail Özgür (Elsevier BV, 2007-08-01)
Exposure conditions significantly affect the resistance of cements to sulfate attack. This article investigates the sulfate resistance of ordinary portland cement (OPC), sulfate resistant portland cement (SRPC), and blended cements with different proportions of natural pozzolan and Class F fly ash when subjected to different exposure regimes. Plain and blended cement mortar specimens were stored under three different conditions: (i) continuous curing in lime-saturated water, (ii) continuous exposure to 5% N...
Sulfate removal from drinking water by commercially available nanofiltration membranes: A parametric study
Karabacak, Aslı; Dilek, Filiz Bengü; Yılmaz, Levent; KİTİŞ, Mehmet; Yetiş, Ülkü (2020-01-01)
© 2020 Desalination Publications. All rights reserved.The efficacy of nanofiltration (NF) in removing sulfate from a high sulfate content (370–460 mg/L) surface water was investigated. NF tests were carried out using a laboratory-scale cross-flow NF module operated in total-recycle (full-recycle) mode. Membranes of varying characteristics; namely, DK-NF (Desal DK: GE Osmonics, USA), DL-NF (Desal DL: GE Osmonics, USA), and NF270 (Dow Filmtec Co., USA) were tested, and the effects of main operational paramete...
