建材产品碳足迹(CFP,CarbonFootprint)是建材产品生命周期中温室气体(GHG)排放的量化值,通常以CO2当量表示;它可以有效反映出建材产品在原材料开采、产品制造、使用和废弃阶段(从“摇篮到坟墓”)整个过程(或部分过程)中温室气体的排放量,同时反映出产品的环境友好程度。由于建材生产是典型的流程型工业,原料类型多、生产流...
This paper presents a feasible way to design a low carbon footprint Ultra-High Performance Concrete (UHPC) with gold tailings based on the idea of full scale recycling. Due to the fact that the particle size distribution of the recycled gold tailings is normally wild, from micrometer to ...

However, the CO2 footprint is far higher for UHPC, compared to equal volumes of conventional concrete [4]. The main reason is the high amount of cement and high-strength steel fibers [4, 5]. Reducing the content of Portland clinker, which is the main binder in most modern cement types ...

Moreover, UHPGC can reduce both the carbon footprint and production cost of footbridge. From studying the fresh, mechanical and microstructural properties of UHPGC by replacing cement and quartz powder with GP (Soliman and Tagnit-Hamou, 2016), a hydration rim around cement and GP particles ...

In certain areas of application, the ecological footprint lies below that of conventional reinforced concrete. However, this can only be ensured if structures are optimized accordingly and the high-performance materials used are fully utilized [10], [20]. In this paper, the structural performance ...
Tools capable of intuitively demonstrating the tradeoffs between mix proportions and mechanical performance are in increasing need for this industry given the embodied carbon footprint associated with typical UHPC compositions. Meanwhile, the ingredients and their proportions required to produce UHPC ...
