“…Liang LI et al [12] carried out a study on calcination and clinkerization differences between raw meal with carbide slag proportion and ordinary raw meal, and found that the cement containing calcium carbide slag had better performance and could reduce energy and resource consumption. Yunfeng ZHOU et al [13] studied the performance of calcium carbide slag and summarized several ways to produce cement using calcium carbide slag. Huageng CHEN [14] studied the cement production by calcium carbide sludge, summed up different production techniques, equipment and solutions to produce cement by using calcium carbide slag replacing or partially replacing limestone with cement slag, and aimed at solving the problem for storage and environmental pollution of calcium carbide slag.…”

The recycling utilization of solid waste is an important technical means for the sustainable development of the cement industry in China. Calcium carbide slag is a special solid waste in China, which can be used for cement production with a great advantage on CO2 emission reduction. With an view to providing methodological and data support for the development of policies in the cement industry, this paper quantitatively analyzes the environmental effects/environmental benefits of the comprehensive utilization of calcium carbide slag in cement kiln by comparing the traditional system of Portland cement clinker completely produced by natural resources with the system of cement clinker produced by calcium carbide slag based on the life cycle assessment (LCA) method given in standards and specifications of ISO 14040 series. The results show that the latter system has a better effect in material saving and carbon emission reduction, will increase the energy consumption in cement production process, and also slightly increase other pollutants (e.g. SOx, NOx, etc.) emission. The GWP, AP and EP indicators of the calcium carbide slag cement clinker system decrease compared with those of the Portland cement clinker system, while other indicators do not differ much or even slightly increase.

“…They can be used to synthesize biodegradable, lightweight, renewable materials that ensure good mechanical properties. Due to the extended functionality of bio-plasticizers over synthetic phthalates ones, the plastic industry is being replacing traditional plasticizers [ 4 , 10 ]. A forecast revealed that the demand of bio-plasticizers would be increasing 9.75 million tonnes in 2024 as mentioned in the Cabot Corp report, 2017.…”

“…Consequently, a number of studies have applied steel slag aggregate for low-carbon asphalt mixtures [15]. In addition to alleviating the environmental impacts, it was found that steel slag asphalt mixtures have good road performance and mechanical properties [16][17][18]; moreover, several studies demonstrated that steel slag showed better apparent morphology and mechanical properties than those of natural aggregate, including wear resistance, antiskid properties, angular richness, and high alkalinity [19,20]. Meanwhile, many studies have investigated the servicing performance of steel slag asphalt mixtures and conventional asphalt mixtures.…”

Recycling reclaimed asphalt pavement (RAP) for asphalt pavement construction is of interest due to its potential to mitigate environmental impact and resource consumption; however, the addition of RAP limits the induction heating behavior of asphalt mixtures, hindering the further application of RAP in sustainable and functional asphalt pavement. This study prepared recycled asphalt mixtures with high contents of steel slag aggregate and RAP, and optimized the rejuvenator dosage and composition design to investigate the induction heating rate. The effect of the steel fiber content, heating time, and heating distance on the induction capacity were verified for the recycled asphalt mixture. Moreover, the cooling curves of the recycled asphalt mixture were explored using a constant temperature chamber and infrared camera. The results showed that 6 wt% of rejuvenator in aged asphalt could evidently restore the physical properties and surface morphology, the highest heating rate of 1.204 °C/s could be reached with 2 wt% of steel fiber content, and the effective intervals of heating time and heating distance were set as 60–120 s and 10–20 mm, respectively. This study could be a significant reference in promoting solid waste recycling and sustainable asphalt pavement construction.
