that the mechanism of GBFS preventing alkali aggregate reaction (AAR) is: when GBFS is dissolved by alkali medium, SiO2 and Al2O3 are dissolved into the cement matrix, then around GBFS particles form...The Mechanism of Ground Granulated Blastfurnace Slag Preventing Alkali Aggregate ReactionSTARK Jochen,FREYBURG ErnstF A Finger-Institute for Building Material Science of Bauhaus-University Weimar摘 要......
characterized by XRD and SEM. The effects of the precursor (CuO, Cu(OH)2), reaction temperature and glucose concentration on morphology of Cu2O particles were investigated, and the mechanism of morphology...) and cubic (c) shapes 4 Discussion 4.1 Shape-controlling mechanism In this work, different shapes of Cu2O crystal particles were obtained via changing the reaction conditions such as the precursor......
mechanisms with Arrhenius reaction rates are implemented in combustion chemistry modeling. On the other hand, a reduced mechanism containing important reactions of ethanol involving heat release rate... temperature and pressure. Moreover, the maximum temperature and pressure are associated with richer mixtures. Key words: HCCI engine; ethanol; two-step reaction mechanism model; chemical kinetic model......
a detailed catalytic surface reaction mechanism with noble metal and promoter elementary reactions, a new three-way catalytic converter (TWC) reaction mechanism is established. Based on the new mechanism... converter; reaction mechanism; numerical simulation; grey relational analysis......
of the minimum free energy, the most reasonable equations were inferred from the possible reactions. Key words: Al; nanocomposites; thermite reaction; reaction mechanism 1 Introduction As a kind... the reaction performance and reaction mechanism was proposed to take the comparison with the results that are obtained under the same condition. In this work, using 1,2-epoxypropane derived sol-gel method, we......
of saturated Fe on the interfacial reaction between solid nickel and liquid zinc are not well understood. In the present work, an attempt has been made to elucidate the mechanism of the dissolution... mechanism involving nickel atom in the intermetallic compound layers and the chemical reaction between solid and liquid[9]. In liquid zinc saturated with Fe, kd is larger that km. Based on the four steps......
