“…The primary chemical components of oil shale wastes are SiO 2 , Al 2 O 3 , and Fe 2 O 3 , which form about 70% of their chemical composition, which complies with ASTM requirements for natural pozzolan and fly ash to be used in concrete [ 39 , 40 ]. This urged the researchers to investigate the cementitious properties of OSAs and their utilization as cement replacement materials.…”

“…The FOSA raw material is usually burned at a temperature of 500–1000 °C, but no information on the burning time and exact temperature is provided [ 48 , 49 , 57 , 58 , 59 ]. Yet, the burning temperature profile should be controlled to ensure the best pozzolanic behavior [ 40 ]. There is hardly any literature on the exclusive use of OS to produce ash under controlled conditions.…”

Fly oil shale ash (FOSA) is a waste material known for its pozzolanic activity. This study intends to investigate the optimum thermal treatment conditions to use FOSA efficiently as a cement replacement material. FOSA samples were burned in an electric oven for 2, 4, and 6 h at temperatures ranging from 550 °C to 1000 °C with 150 °C intervals. A total of 333 specimens out of 37 different mixes were prepared and tested with cement replacement ratios between 10% and 30%. The investigated properties included the mineralogical characteristics, chemical elemental analysis, compressive strength, and strength activity index for mortar samples. The findings show that the content of SiO2 + Al2O3 + Fe2O3 was less than 70% in all samples. The strength activity index of the raw FOSA at 56 days exceeded 75%. Among all specimens, the calcined samples for 2 h demonstrated the highest pozzolanic activity and compressive strength with a 75% strength activity index. The model developed by RSM is suitable for the interpretation of FOSA in the cementitious matrix with high degrees of correlation above 85%. The optimal compressive strength was achieved at a 30% replacement level, a temperature of 700 °C for 2 h, and after 56 days of curing.

“…Over the past decade, a large body of work has been dedicated to oil shale-related science and technology research, while the object and content of these studies have been very complex. Some investigations have reviewed the oil shale research status from a certain technical aspect or a certain country's perspective [17][18][19][20][21]. However, the changing world energy situation requires a more systematic characterization of progress, hotspots and trends in oil shale research.…”

The world energy mix has been confronted with significant challenges since the international circumstances became increasingly complicated. Oil shale is a typical alternative resource to traditional oil, therefore, it is of great significance to re-evaluate its exploitation and utilization status and research trend under the new background. Through the bibliometric analysis of 944 articles on oil shale published between 2012 and 2022 collected from the Web of Science (WoS) database, this research has carried out a review on the global publication and research trend in oil shale relevant studies. It then investigated and compared the research characteristics in three major countries that carry out oil shale related research, to identify the opportunities of oil shale development in different nations under the restriction of diversified factors. The results show that during the last ten years, research on oil shale has experienced a continuous growth in publication quantity and greatly contributed to the oil shale development with the production of highest cited studies. As for the regional characteristics, Estonia focuses on the comprehensive utilization of oil shale and stands out in its engagement in the environment protection, while China and the United States are still accumulating the applied technological research and fundamental science knowledge and conservatively develop the utilization of oil shale. Although different regions have developed different

“…Chemically, the OSA contains high calcium oxide content that is, naturally, suitable for cement production itself [6,12]. In addition, OSA also contains SiO 2 and Al 2 O 3 that both can demonstrate pozzolanic activity (6).…”

The energy crisis is one of the major challenges confronting the cement industry today. Although non-renewable energy sources are becoming scarce, the presence of significant quantities of oil shale indicates its continued use as an energy source in the cement industry. However, significant environmental impacts may occur as a result of the large amount of oil shale ash (OSA). As a result, the researchers are investigating alternative methods for recycling and reusing the OSA in a variety of applications. The purpose of this work was to use OSA as a green substitute component in cement production due to its high calcium oxide (CaO) content, which is the major component of cement clinkers. The chemical composition of OSA and Clinker samples were determined using X-ray fluorescence (XRF) and X-ray diffraction (XRD). OSA and clinker samples were combined in various ratios and then ground in a ball mill to obtain the desired grain size. The new blended products were prepared and tested at Lafarge factory's laboratories. The results indicated that by adding 10% of OSA to the clinker, the mixed product performed better than the reference sample. Additionally, using this percentage of OSA results in a 45% reduction in the power consumption of the grinding process compared to the reference sample.
