This paper deals with the study of calcium sulfoaluminate (CSA) and geopolymeric (GEO) binders as alternatives to ordinary Portland cement (OPC) for the production of more environmentally-friendly construction materials. For this reason, three types of mortar with the same mechanical strength class (R3 ≥ 25 MPa, according to EN 1504-3) were tested and compared; they were based on CSA cement, an alkaline activated coal fly ash, and OPC. Firstly, binder pastes were prepared and their hydration was studied by means of X-ray diffraction (XRD) and differential thermal-thermogravimetric (DT-TG) analyses. Afterwards, mortars were compared in terms of workability, dynamic modulus of elasticity, adhesion to red clay bricks, free and restrained drying shrinkage, water vapor permeability, capillary water absorption, and resistance to sulfate attack. DT-TG and XRD analyses evidenced the main reactive phases of the investigated binders involved in the hydration reactions. Moreover, the sulfoaluminate mortar showed the smallest free shrinkage and the highest restrained shrinkage, mainly due to its high dynamic modulus of elasticity. The pore size distribution of geopolymeric mortar was responsible for the lowest capillary water absorption at short times and for the highest permeability to water vapor and the greatest resistance to sulfate attack.

“…On the other hand, efforts have been dedicated to designing lowcarbon cement. Incorporation of industrial wastes, such as, waste glasses (Shi and Zheng, 2007), recycled concrete waste (Gastaldi et al, 2015;Oh et al, 2014), oil-based mud (Abdul-Wahab et al, 2016;Bernardo et al, 2007), arc furnace steel slag (Bernardo et al, 2007;Iacobescu et al, 2011) and contaminated soil (Navia et al, 2006) into the clinker process, are found to be feasible to reduce the CO 2 emissions of cement manufacturing.…”

a b s t r a c tTo devise low-carbon cement clinker product, in-depth knowledge about the variation mechanism of cement clinker CO 2 emissions is the prerequisite. The determinants of cement clinker CO 2 emissions in Chinese cement industry have been inquired by several researches recently. However, the impacts and abatement effect of clinker quality on cement clinker CO 2 emissions have not been identified yet. In technological sense, there lacks an integrated quantitative model that can elucidate the dynamic mechanism between cement clinker CO 2 emissions and clinker quality. To fill this gap, this paper devises a CO 2 emission accounting framework integrated with optimization model to explore the dynamic mechanism between cement clinker CO 2 emissions and clinker quality. Based on survey data of 2 typical cement clinker production lines in China, the accounting framework is validated with measured data. Through numerical simulation within this framework, a set of sensitivity analysis is conducted. The results indicate that if the target KH (lime saturation ratio) of both production lines climb from −5% to +5%, the process CO 2 emission factor will give rise to an increase of about 16.4 and 14.8 kg CO 2 /t clinker, respectively. With the same variation, the fuel CO 2 emission factors of two production lines will gain 17.2 and 13.7 kg CO 2 /t clinker, respectively. Obviously, controlled decrease of clinker quality can reduce CO 2 emission of clinker manufacturing. The results of sensitivity analysis are robust and highlight the remarkable role of clinker quality in both process and fuel emissions. Besides, the integrated framework can provide in-depth investigation into the dynamic mechanism between CO 2 emissions and the other determinants. Using this framework, cement plants or industry can develop optimal clinker quality standards on a quantitative basis to achieve low-carbon clinker.

“…The technical, economic, and environmental effects of using alternative fuels and raw materials in clinker manufacturing have received considerable attention in recent years [1][2][3]. In particular, the use of waste or by-products as raw material substitutes during its manufacturing has been studied heavily because these substitutes can lead to significant savings of natural resources [2,4].…”
