摘要

水泥基复合材料是多孔材料,因此在设计过程中控制其孔隙率对于确保复合材料的质量和强度至关重要。最近,随着减少水泥基复合材料碳足迹的紧迫性日益增加,新型外加剂已被引入作为水泥的替代品。每次采用新型外加剂时,都需要开展一项研究活动来评估填料密度。传统的评估方法耗时长、成本高,而且会造成浪费。利用神经网络实施无浪费解决方案是一种很有前途的替代方法。作者分析了在复合材料中用粉煤灰和花岗岩粉替代水泥的效果,最高可达水泥用量的 30%。此外,他们还设计了一个神经网络模型来预测这些混合物的堆积密度。通过生命周期评估分析,证明了这种方法的实用价值。

Smart optimization of packing density for cleaner production of cementitious composites using mineral powders

Smart optimization of packing density for cleaner production of cementitious composites using mineral powders

Cementitious composites are porous materials; therefore, controlling their porosity during the design process is crucial to ensuring the quality and strength of the composite. Recently, with the growing urgency to reduce the carbon footprint of cementitious composites, novel admixtures have been introduced as substitutes for cement. Each time a novel admixture is implemented, a research campaign is required to evaluate packing density. Traditional methods used for this purpose are time-consuming, costly, and generate waste. Implementing a waste-free solution using neural networks is a promising alternative. The authors present an analysis of the effectiveness of substituting cement with fly ash and granite powder up to 30% of the cement volume in composites. Additionally, they designed a neural network model to predict the packing density of these mixtures. The practical value of this approach was demonstrated through life cycle assessment analyses.
