Determination of the pozzolanic activities of trachyte and rhyolite and comparison of the test methods implemented
(Springer International Publishing Ag, 2020)
Natural pozzolanas should be evaluated in terms of sustainability as well as their contribution to concrete durability. Therefore, the use of such materials in the production of cement as well as concrete industry has been ...
Finite element modeling of contact between an elastic layer and two elastic quarter planes
(Techno-Press, 2020)
In this study, a two dimensional model of receding contact problem has been analyzed using finite element method (FEM) based software ANSYS and ABAQUS. For this aim finite element modeling of elastic layer and two homogeneous, ...
Synthesis and characterization of activated carbon produced from waste human hair mass using chemical activation
(Springer Japan Kk, 2020)
In this study, hair waste was converted into active carbon for the first time and its characteristics were analyzed. As chemical activation tool, zinc chloride (ZnCl2) was impregnated and then carbonized under different ...
Enhanced performance figures of solar cookers through latent heat storage and low-cost booster reflectors
(Oxford Univ Press, 2020)
Solar box cookers draw attention of many researchers across the globe as a promising renewable energy application for cooking purposes. Compared to other types available in literature, solar box cookers are more in the ...
Influence of hydrofluoric acid leaching and roasting on mineralogical phase transformation of pyrite in sulfidic mine tailings
(Mdpi, 2020)
Under the oxidative roasting process, pyrite, as a major mineral in sulfidic mine tailings, can transform to iron oxides. Generated iron oxides, if exhibiting enough magnetic properties, can be recovered via magnetic ...
