| الوصف: | A number of beneficial characteristics are displayed by ordinary Portland cement (OPC), including workability, appropriate setting and hardening behavior, superior mechanical performance, and good chemical resistance. OPC has been used as the major bonding agent in the building industry for more than 200 years due to these reasons. OPC is commercially produced by heating limestone, quartz, clay, and slag in a specially designed rotary kiln. The goal of this study is to use waste materials (construction and demolition waste) and alternative clayey materials to produce cement clinker. When it comes to the resources needed to make cement clinker, caution has been applied because substitute raw materials need to be accessible in adequate quantity and quality. Carbon dioxide is a byproduct of the chemical reactions in a rotary kiln. One kilogram of CO2 is released into the atmosphere during the cement-making process. Up to 9% of global human CO2 emissions are produced annually by the manufacture of cement and concrete. An attempt has been made to decrease the sintering temperature and the duration of thermal treatment in order to decrease the carbon emissions of the process. Therefore, in this study, cement clinker was synthesized at temperatures ranging from 1100°C to 1400°C upon mechanical activation of the raw material. Four cement clinkers were produced based on different raw materials: 1) recycled concrete, kaolinitic-illitic clay, Fe-slag, and limestone; 2) recycled concrete, zeolite, Fe-slag, and limestone; 3) recycled concrete, bentonite, Fe-slag, and limestone; and 4) recycled concrete, refined kaolinitic-illitic clay, Fe-slag, and limestone. The obtained clinkers were characterized by DTA/DCS/TG, XRD, FTIR, and SEM methods. The results indicated that the obtained clinkers exhibited four main cement clinker phases, namely C3S, C2S, C3A, and C4AF, identical to commercial ordinary Portland cement (OPC). The obtained results pointed out that the production of cement clinker based on recycled waste resources and ... |
