The environmental impact of lightweight aggregate concrete block, which use fly ash ceramic, was analyzed. The results show that AP and GWP are the most significant environmental impact categories accounting for 30% and 25% of the total environmental impact respectively. The results also show that, in different life cycle phases, the environmental load of the lightweight aggregate concrete block is mainly caused by the production of cement, which accounts for 42% of the total environmental impact.

The environmental impacts of cement production using two pre-drying processes, i.e., coal-fired pre-drying process and pre-drying process by waste heat from kiln tail process were analyzed and compared through life cycle assessment (LCA). The results show that the energy consumption, GWP, AP, POCP, HT and EP of pre-drying process by waste heat from kiln tail are about 1%, 2%, 5.2%, 5% ,3.5% and 3.8% lower than coal-fired process; therefore the application of pre-drying process by waste heat from kiln tail has obvious environmental benefits.

Life cycle assessment (LCA) was carried out to quantify and analyze the environmental impact and benefit caused by the utilization of coal gangue as alternative raw material and fuel in cement clinker production. The optimal dosage of coal gangue was determined by comparing among different mixing amount scenarios and Portland cement clinker (clinker without adding any waste) considering the phases of coal gangue disposal, transportation, and raw meal grinding and clinker calcination. The results showed that: 1) After adding coal gangue to the raw meal, almost all the considered environmental impacts of cement clinker including human toxicity potential, photochemical smog potential, especially abiotic depletion potential decreased significantly. However, global warming potential and acidification potential increased slightly in comparison with Portland cement clinker. 2) Compared with the Portland cement clinker, the single environmental indicator reduced after adding coal gangue and the indicator decreased gradually with the dosage increasing.

In this work, (Fe,Co)–Zr–B–Cu films have been deposited on glass and Si substrates by DC magnetron sputtering method. X-ray diffraction analysis was used to identify the structure of the films. A transmission electron microscope (TEM) was employed to observe the microstructure for the films. Magnetic properties at room temperature were investigated by a Vibrating Sample Magnetometer (VSM). It was obtained that the as-deposited films on glass and Si substrates were in an amorphous state. In addition, it has been found that the coercivity is dependent on film thicknesses.
