“…The national average emission factor estimated in 2030 is 715.33 kg/t, a decline of 16.65% compared to that in 2015. The emissions reduction estimated by Wei et al (2019) over the period 2018-2030 (158.50 kg/t) were higher than those in the present study (142.85 kg/t), as a higher diffusion rate of raw material (~21%) and fuel substitution (~42%) in 2030 was used. In 2030, the clinker emission factors of the 13 surveyed provinces were higher than the national average level.…”

Detailed analysis the disparity and reduction potential of clinker emission factors at the provincial level is important for regional reduction policies. Using the surveyed data from 185 new suspension and pre-heater (NSP) process lines and 69 Shaft kiln lines, this study firstly analyzed the disparity in emission factors based on production process, production scale, and regional distribution in 2015. We found that the emission factor of the Shaft kiln process (898.24 kg/t) is higher than that of the NSP process (858.59 kg/t), 16 and that small-scale production lines have higher emission factors than large-scale lines both for the two 17 process. China's clinker emission factors increase from the eastern to the western regions. Then we 18 estimated the reduction potential of structural adjustment, raw material substitution, and energy saving and 19 fuel substitution in regional emission factors by 2030. The result shows that emission factors of the 20

“…Cement industry is responsible for about 7% of the global CO2 emissions and the third largest industrial energy consumers [1]. It is also responsible for about 10% of the total CO2 emissions in China [2]. China produces more than 60% of global cement, which is mainly driven by the economic, population, and urbanization growth.…”

“…Based on Building and Infrastructure Construction (BIC), Peak consumption Per capita (PCPC), and Fixed Assets Investment (FAI), respectively, Ke et al [10] predicted that the cumulative cement production in China would be 26.0 Gt, 35.9 Gt and 35.0 Gt from 2011 to 2030. Based on fixed assets investment, urbanization rate and per capita GDP, respectively, Wei et al [2] projected China's cement production would reach 2,000 Mt, 1,650 Mt and 937 Mt by 2030. Recently Hache et al [11] studied the impacts of future power generation on cement demand based on climate scenario on a global level, while Elshkaki [12] has estimated cement demand, among oter materials, required for the future electricity generation in China based on several national and international scenarios.…”

“…Although there are several studies addressing cement industry and associated CO2 emissions, China's long-term cement demand and related energy and CO2 emission were not fully studied [2]. In this paper, we analyse the historical demand for cement based on socio-economic, technology, and policy related factors and develop several long term scenarios for cement-energy-CO2 emissions nexus up to 2050.…”

With rapid urbanization and the requirements for new buildings and infrastructure, cement production is expected to increase in China. Meanwhile, China's energy consumption and carbon emissions associated with cement industry are expected to increase, as cement production is one of the most energy intensive industries. Introducing new and more pertinent technologies with better management, as indicated by government goals and measures, can improve energy efficiency and reduce carbon emission. However, many challenges and uncertainties in the cement industry have been addressed without considering several interconnected processes among sectors including industry, energy, construction, and services, which lead to little improvements in the industry. Nexus approaches are recognized as effective methods to simultaneously

“…In China, the cement industrial production has reached 2.4 billion tons in 2017, 125% higher than 2005, accounting for 58% of global cement output, and such situation is expected to continue in the next few decades [2]. However, cement production is a high-cost, energy-consuming, and pollution-intensive process [3][4][5]. erefore, in order to reduce the greenhouse gas emissions and achieve sustainable environmental development, it is necessary to develop alternatives to Portland cement to reduce both CO 2 emissions and energy consumption.…”

Alkali-activated slag (AAS) is becoming an increasingly popular building material due to its excellent engineering properties and low CO 2 emissions, but its large shrinkage is an important reason to restrict its application and popularization. is work is aimed to study the possibility of inhibiting the shrinkage of AAS mortar by incorporating polypropylene fiber (PPF). For this, an experimental study was carried out to evaluate the effects of PPF content on setting time, fluidity, physical properties, mechanical properties, impact resistance, and microstructure of AAS mortar. e volume content of PPF is 0.05%, 0.1%, 0.15%, and 0.2%. e working, physical (porosity, water absorption, and bulk density), mechanical, shrinkage, and impact resistance properties of the AAS mortars were evaluated. e results show that incorporating PPF effectively reduces the shrinkage deformation of AAS mortar, significantly improves its impact resistance, enhances its toughness, and slightly improves its compressive strength in the later stage. At the same time, PPF delays the initial setting time of AAS mortar and reduces the fluidity, density, porosity, and water absorption of AAS mortar. SEM results show that the bridging effect of PPF between AAS mortars can inhibit the generation and propagation of cracks, improve the internal microstructure, and enhance the performance of AAS mortar.
