Study of deterioration of concrete exposed to different types of sulfate solutions under drying-wetting cycles
Lei Jiang,Ditao Niu +1 more
TL;DR: In this paper, the properties of concrete subjected to drying-wetting cycles in different types of sulfate solutions were investigated, and the results showed that the deterioration degree of concrete in magnesium sulfate solution is more severe than that in the other sulfate compounds.
Journal ArticleDOI
Durability of concrete under sulfate attack exposed to freeze–thaw cycles
TL;DR: In this article, the properties of concrete (with additional 20% fly ash) subjected to freeze-thaw cycles in water and in sulfate solutions were investigated, and the deterioration considering the weight loss, relative dynamic modulus of elastically (RDME) loss and compressive strength loss of concrete under the coupling effect were also investigated.
Journal ArticleDOI
Concrete Deterioration Mechanisms under Combined Sulfate Attack and Flexural Loading
TL;DR: In this article, the deterioration mechanisms of sulfate attack on concrete under sustained loading and wet-dry cycling were investigated, based on micro and macroobservations, and the results showed that concretes are attacked by expansive products such as ettringite and gypsum during the wetting cycle, and crystallization damage, induced by evaporation, is superposed during the drying cycle.

Evaluation of Cu-based oxygen carrier for chemical looping air separation in a fixed-bed reactor
TL;DR: In this paper, the feasibility of CuO in steam atmosphere was evaluated by thermodynamics, and the oxygen release and absorb rates of the four oxygen carriers were determined under reduction temperatures of 950, 975 and 1000 °C and oxidation temperatures of 800, 850, 900 ÂC in a fixed-bed reactor.

Relationship between transformation temperatures and alloying elements in Cu–Al–Ni shape memory alloys
Z. Karagoz,C. Aksu Canbay +1 more
TL;DR: In this paper, the effects of alloying elements on transformation temperatures, heat-capacity values, and structural properties of Cu−13.73Al−4.3Ni (wt%) shape memory alloys are investigated.
