Cement is an essential construction material and its production and demand are becoming challenge for environmental (carbon dioxide emission) and sustainability (natural resources consumption) related issues. The sustainable alternative is a key requirement to fulfill the increasing demand for natural resources and reduction in carbon dioxide (CO 2 ) emission. For sustainable development, ash generated from the thermal treatment of sewage sludge (SSA) and carbide lime sludge (CLS) has been used for the production of green cement. For the feasibility study, the influence of using SSA and CLS are compared in terms of the properties of fresh paste and hardened mortar with Portland Pozzolana cement (PPC) containing FA. The outcome of the study shows that up to 45% of ordinary Portland cement can be replaced by using SSA with CLS blends, which enhance the compressive strength, save the natural resources and reduce CO 2 emission up to 52% when compared with FA substitution.

“…Concerning the factors such as preparation cost, the internal temperature increase in the bulk FLS, volume stability, and durability, Specimen D (30% cement, 30% GBFS and 40% FA) is recommended. If we consider CO 2 emissions to the atmosphere from the production of cement [ 23 ], based on a calculation that for every 1 t of cement produced, approximately 0.7 t of CO 2 is emitted to the atmosphere [ 24 ], using sample A would emit approximately 241.5 kg of CO 2 , sample B or sample C would emit approximately 144.9 kg of CO 2 [ 25 ]. In comparison, sample D would only emit 72.5 kg of CO 2 per 1 t. It concludes that using sample D would emit 70% less CO 2 than using sample A.…”

The foamed lightweight soil (FLS) with superior performance was prepared to be used as a subgrade filling material in an intelligent networked vehicle test site. The production process of practical engineering FLS is simulated in the laboratory. The performance of the prepared FLS is the same as that of practical engineering. The test results show that the FLS prepared with 30% cement, 30% granulated blast furnace slag, and 40% fly ash as cementing material has a flow factor of 175 mm. It has good fluidity and is easy to pump. Wet density reaches 593 kg/m3 within the range of the control index of 600 ± 30 kg/m3. The compressive strength of 7 d and 28 d reaches 0.82 MPa and 1.90 MPa, respectively, which is higher than the design strength of 0.5 MPa and 1.0 MPa. Compared with FLS made of pure cement as a cementing material, the FLS has a low heat of hydration, good volume stability, no cracks on the surface, excellent sulfate resistance, good economy, and low carbon characteristics. In the meantime, it can reduce 70% CO2 emissions in cement production. The advanced vehicle-mounted mobile intelligent control system is flexible and convenient in actual engineering construction. It can display the wet density of FLS online, which is easy to adjust and control to ensure the quality stability of FLS.

CO₂ emissions from the Chinese cement sector: Analysis from both the supply and demand sides

China is the largest producer and consumer of cement worldwide, and cement production entails the release of substantial carbon dioxide (CO 2) emissions. As the cement sector is a crucial sector of the Chinese economy, understanding the role of supply-and demand-side factors may help accelerate efforts to mitigate CO 2 emissions. However, few studies have analyzed the critical factors affecting CO 2 emissions in the sector based on a combined supply-and demand-side perspective. In this study, we developed an integrated framework that included eleven indicators covering both the supply and demand sides. Results revealed that improving cement production technology cannot offset CO 2 emissions from the growth in demand for cement. Improving technology on the supply side would considerably reduce CO 2 emissions from Chinese cement production; nevertheless, the combination of rapid urbanization, GDP growth, and an ultra-high fixed capital formation ratio on the demand side increased CO 2 emissions nearly 25-fold from 1990 to 2015. Notably, some demand-side factors also had an effect that reduced CO 2 emissions. The in-use stock per unit of fixed capital formation and output per in-use stock reduced CO 2 emissions by 332 million metric tons, which is comparable to the contribution of technological progress. Based on these results, we examine why these demand-side factors substantially influence CO 2 emissions in the Chinese cement sector, and we provide recommendations for policy-makers on carbon-reduction measures in this CO 2-intensive sector.
