“…The adoption of supplementary cementitious materials (SCM) in the construction industry has become widespread and a major trend among developed and developing countries. − With the recent focus on developing low-CO 2 cementitious composites, there has been an unprecedented shift to SCMs research. − The main SCMs commercially available are fly ash (FA), , silica fume (SF), , and ground-granulated blast furnace slag (GGBFS). − However, conventional SCMs currently face challenges associated with insufficient production and geographical scarcity, mainly due to the greening of other industries and the closing of coal-powered plants for blended cements. − …”

In support of the greening of the construction industry, the development of alternative composites with equal capabilities is paramount. In this study, the pozzolanic activity of poultry litter ash (PLA) calcined at three distinct temperatures (600, 700, and 800 °C) was determined by two direct methods: Frattini and Chapelle. Supporting physicochemical techniques were used to evaluate the properties and suitability of PLA as a pozzolan. The elemental composition of PLA is assessed by CHNS-analysis, while Fourier transform infrared (FTIR) spectroscopy shows functional groups. Calcium oxide is the most significant crystalline phase in the 700−800 °C temperature range. Pozzolanic tests yielded significant results in terms of Ca(OH) 2 consumption for samples calcined at 700 and 800 °C: CaO reductions above 34 and 20% in the Frattini test and 240.46 and 107.87 mg Ca(OH) 2 /g PLA in the Chapelle test, respectively. Frattini and Chapelle tests may be affected due to calcium compounds leaching and are not appropriate for CaO-dominant materials.

“…The continued demand for cement-based materials by the construction industry leads to the intense exploitation of natural resources and to high CO 2 emissions [13]. As a strategy to mitigate this problem, BOF slag has been researched as an alternative material [4,[14][15][16][17]. Using this by-product of the steel industry as an efficient alternative to ordinary Portland cement (OPC) would be a significant contribution to the circular economy, thereby increasing the rational utilization rate of resources.…”

“…However, when the curing temperature and the curing age are lower than 40 • C and 28 days, respectively, the mechanical strengths are decreased by the addition of mineral admixtures [18]. The alkali slag cement-based material has become a popular green and environmentally friendly material studied at home and abroad [19,20]. This kind of material shows excellent mechanical strengths when cured in several curing environments and curing ages [21,22].…”

In this paper, the influence of water glass types, the modulus of water glass, the alkali content, the water consumption, and plant fibers on the mechanical strengths of alkali-activated blast furnace slag powder (BFS) is investigated. Moreover, the fiber types and pretreatment on the plant fibers and the measuring temperature on the performance of alkali-activated BFS are further considered. Results indicate that BFS activated by potassium silicate shows higher mechanical strengths than that activated by sodium silicate. The alkali-activated BFS with alkali treatment on fibers is the most advantageous. The modulus of alkali leads to decreasing the compressive strength. A total of 35% water consumption is the most beneficial to the specimens’ flexural and compressive strengths. Samples with 14% potassium silicate show the maximum mechanical strength. Alkali-activated BFS with 1% wheat straw fibers in addition by total volume represents the maximum mechanical strength. The alkali-activated BFS with alkali treatment on fibers is the most advantageous. The addition of potassium silicate can improve the flexural and compressive strengths by the maximum values of 30.4% and 16.8% compared to specimens with sodium silicate. A total of 35% water consumption can increase the flexural and compressive strengths by 33.8% and 32.7%.
