A comprehensive evaluation of sedimentary zeolites from Turkey as pozzolanic addition of cement- and lime-based binders
(Elsevier Sci Ltd, 2016)The pozzolanic action played by five natural zeolite-rich materials (three clinoptilolite- and one each mordenite- and analcime-bearing rocks) coming from Turkey, has been examined, evaluating also the influence of various ... -
Compressive strength and microstructural characteristics of natural zeolite-based geopolymer
(Budapest Univ Technology Economics, 2018)A detailed study of geopolymeric reaction products and mechanical properties of geopolymer pastes prepared with natural zeolite has been investigated by means of compressive strength, XRD and SEM/EDX analysis. Sodium ... -
Cordierite-bearing strongly peraluminous cebre rhyolite from the eastern Sakarya Zone, NE Turkey: Constraints on the variscan orogeny
(Elsevier, 2017)The Cebre Rhyolite with an outcropping area up to 12 km(2) is one of the rare extrusions in the Variscan basement of the Sakarya Zone. the unit consists of high-K calc alkaline rhyolites (SiO2 = 74-82 wt.%). Abundant ... -
Crustal evolution of NW Iran: Cadomian arcs, archean fragments and the cenozoic magmatic flare-up
