Zhang, Yu (author), Copuroglu, Oguzhan (author)The properties of slag-rich cement paste are fundamentally associated with slag chemistry. In the present research, 10 slags covering the common chemistry range, including eight synthetic slags of CaO-SiO2-Al2O3-MgO system and two commercial slags, were adopted to evaluate the influence of slag composition on the early (7 days) and later (3...journal article 2023

Hu, L. (author), Pinto, D. (author), Urakawa, A. (author)Direct valorization of methane via oxidative coupling of methane (OCM) is an encouraging alternative to conventional oil-based processes for the production of light hydrocarbons (ethane and ethylene). Abundant, inexpensive simple oxides such as MgO and La<sub>2</sub>O<sub>3</sub> possess the ability to selectively activate methane. However,...journal article 2023

Zhang, Y. (author)In order to compensate the limited availability of raw material resources and meet the growing demand for decreasing CO2 emissions during cement and concrete productions, a practical method is to decrease the clinker content in cement. This strategy mainly consists of substituting a part of the clinker with supplementary cementitious materials ...doctoral thesis 2022

Zhang, Y. (author), Liang, M. (author), Gan, Y. (author), Copuroglu, Oguzhan (author)This paper reports the carbonation characteristics of a cement-slag system exposed to accelerated carbonation testing, and its improved carbonation resistance with the increasing MgO content in blast furnace slag, in which hydrotalcite-like phase plays a key role. Our research showed that the hydrotalcite-like phase started to carbonate upon...journal article 2022
