In recent years, the application of fractal theory in construction materials has drawn tremendous attention worldwide. This special issue section containing seven papers publishes the recent advances in the investigation and application of fractal-based approaches implemented in construction materials. The topics covered in this introduction mainly include: (1) the fractal characterization of construction materials from nano- to micro-scales; (2) combining fractals methods with other theoretical, numerical and/or experimental methods to evaluate or predict the macroscopic behavior of construction materials; (3) the relationship of fractal dimension with the macro-properties (i.e. mechanical property, shrinkage behavior, permeability, frost resistance, abrasion resistance, etc.) of construction materials.

社论：建筑材料中的分形简介

近年来，分形理论在建筑材料中的应用引起了全世界的广泛关注。这个包含七篇论文的特刊部分发表了在建筑材料中实施的基于分形的方法的调查和应用方面的最新进展。本导论涵盖的主题主要包括：（1）建筑材料从纳米到微米尺度的分形表征；(2) 将分形方法与其他理论、数值和/或实验方法相结合，评估或预测建筑材料的宏观行为；(3)分形维数与建筑材料宏观性能(即力学性能、收缩性能、渗透性、抗冻性、耐磨性等)的关系。
