“…When plant-based protection methods are not suitable, particularly for rock slopes, engineering protection techniques are utilized [38]. The primary methods of engineering protection include mortar plastering [39], pointing or spraying [40], and stone slope treatment or the use of facing walls [41]. Figure 2 presents the main engineering protection technologies of slope, currently.…”

Life cycle assessment (LCA) plays an increasingly important role in environmental management, particularly in promoting energy and carbon-conscious practices across various disciplines. This review provides an overview of the latest innovations and potential benefits of integrating LCA into ecological slope treatment strategies. This study explores new developments in LCA methodology and its application to slope treatment, aiming to improve the integration of infrastructure development and environmental stewardship. Through an extensive review of over 120 peer-reviewed journal articles and a critical analysis of the intersection of LCA with slope treatment, this paper identifies innovative techniques that have the potential to significantly reduce the environmental impact of slope management. The review emphasizes advanced LCA practices that quantify and mitigate carbon emissions throughout the life cycle stages of slope treatments. Key findings demonstrate that LCA enhances the methodological rigor in assessing ecosystem services and impacts, and reveals new strategies that emphasize the importance of ecological considerations in infrastructure projects. Future research directions focus on refining LCA data acquisition and promoting a standardized knowledge base to support precision in ecological impact assessments. In conclusion, the adoption of LCA in slope treatment is imperative for aligning industry practices with global sustainability targets, emphasizing the importance of integrating uncertainty analysis and long-term impact assessments to bolster the credibility of LCA outcomes.

“…Portland çimentosu üretiminde; büyük miktarda enerji ve hammadde tüketilmekte, bunun yanı sıra küresel ısınmaya neden olan çok miktarda CO2 salınımına neden olmaktadır [1]. Bu nedenle çimento endüstrilerinden kaynaklanan CO2 emisyonlarını en aza indirmek için silis dumanı [2], uçucu kül [3], yüksek fırın cürufu [4] gibi yapay, yada tras [5], zeolit [6], diatomit [7], pomza [8] gibi doğal puzolanik malzemeler kullanılmaktadır.…”

Bu çalışmada, çimento hamurlarının priz sürelerinin tahmini için uyarlamalı ağ tabanlı bulanık çıkarım sistemi (ANFIS) ile tahmin modelleri geliştirilmiştir. Bu amaçla, Portland çimentosuna %0, %2.5, %5, %7.5 %10, %12.5 ve %15 oranlarında pirinç kabuğu külü ikame edilmiş olan çimento hamurlarının priz başlangıç ve priz sonu süreleri belirlenmiştir. Deneylerden elde edilen sonuçlarla gauss ve üçgen üyelik fonksiyonları kullanılarak iki model oluşturulmuş, bu modeller yardımıyla da priz başlangıç ve priz sonu süreleri tahmin edilmiştir. Modellerden elde edilen sonuçlarının güvenilirliği anlayabilmek için R2, MAPE ve RMSE’den oluşan üç farklı istatiksel yöntemden faydalanılmıştır. İstatistiksel endeksler bir bütün olarak değerlendirildiğinde, priz başlangıç ve priz sonu süreleri açısından hem gauss hem de üçgen üyelik fonksiyonlarıyla oluşturulan modellerle gerçek değerlere çok yakın sonuçlar elde edildiği belirlenmiştir. Dolayısı ile her iki modelin de priz sürelerini tahmin etmek için güçlü modeller olduğu ifade edilebilir.

This study aimed to obtain and characterize a mortar with perlite aggregate and thermal-treated materials that could substitute for Portland cement. First, the thermally treated materials were obtained by calcinating old Portland cement (OC-tt) and concrete demolition waste (CC-tt) at 550 °C, for 3 h. Second, plastic mortars with a perlite: cement volume ratio of 3:1 were prepared and tested for water absorption, mechanical strength, and thermal conductivity. The microstructure was also analyzed. Portland cement (R) was partially substituted with 10%, 30%, and 50% OC-tt. Thermal-treated materials negatively influenced the compressive and flexural strengths at 7 and 28 days. With an increase in the substitution percentage to 50%, the decrease in the compressive strength was 40% for OC-tt and 62.5% for CC-tt. The presence of 10% OC-tt/CC-tt positively influenced the water absorption. The thermal conductivity of the tested mortars was in the range of 0.37–0.48 W/m·K. SEM analysis shows the expanded perlite pores remained unbroken.
