本文从微观和宏观两个层面研究了不同矿渣含量对水泥浆体和路面性能的影响。在微观层面上，对不同BFS掺量和不同水养护时间的水泥浆体的强度和化学性能进行了评价。在宏观层面上，对机场混凝土路面的结构性能和可持续性能进行了研究。在这方面，制定了几个结构设计图，以确定各种飞机设计和路基强度所需的混凝土板的厚度。混凝土路面的可持续性根据燃料需求和温室气体（GHG）排放进行了评估。此外，还提出了一种简单的图形方法，用于比较混凝土路面的结构和环境性能，包括BFS含量、路基强度、不同版本的飞机设计、燃料需求和路面施工的温室气体排放。在此基础上，结合结构分析和可持续性分析，提出了初步BFS内容选择方案。
In this study, the effects of various blast furnace slag (BFS) contents on the performance of cement pastes and pavement were investigated at two levels, the micro and the macro. At the micro level, the strength and chemical properties of cement pastes containing various percentages of BFS and subjected to different water curing periods were evaluated. At the macro level, the structural and sustainability performance of airport concrete pavements were studied. In this regard, several structural design charts were developed to determine the thickness of the concrete slab required to withstand traffic loadings for various versions of aircraft design and subgrade strengths. The sustainability of the concrete pavements was assessed in terms of fuel requirements and greenhouse gas (GHG) emissions. In addition, a simple graphical method was proposed for comparing structural and environmental performance of concrete pavements with respect to BFS content, subgrade strength, different versions of the aircraft design, fuel requirements and GHG emissions for pavement construction. Based on the results obtained using the proposed method and the structural and sustainability analyses, scenarios are suggested for choosing preliminary BFS content.
