Massive volcano-related materials (VRMs) erupted from volcanoes bring the impacts to natural environment and humanity health worldwide, which include generally volcanic ash (VA), volcanic pumice (VP), volcanic tuff (VT), etc. Considering the pozzolanic activities and mechanical characters of these materials, civil engineers propose to use them in low carbon/cement and environment-friendly concrete industries as supplementary cementitious materials (SCMs) or artificial/natural aggregates. The utilization of VRMs in concretes has attracted increasing and pressing attentions from research community. Through a literature review, this paper presents comprehensively the properties of VRMs and VRM concretes (VRMCs), including the physical and chemical properties of raw VRMs and VRMCs, and the fresh, microstructural and mechanical properties of VRMCs. Besides, considering environmental impacts and the development of long-term properties, the durability and stability properties of VRMCs also are summarized in this paper. The former focuses on the resistance properties of VRMCs when subjected to aggressive environmental impacts such as chloride, sulfate, seawater, and freezing-thawing. The latter mainly includes the fatigue, creep, heat-insulating, and expansion properties of VRMCs. This study will be helpful to promote the sustainability in concrete industries, protect natural environment, and reduce the impacts of volcano disaster. Based on this review, some main conclusions are discussed and important recommendations regarding future research on the application of VRMs in concrete industries are provided.
火山喷发产生的大量火山相关物质（VRMs）给全球自然环境和人类健康带来影响，这些物质通常包括火山灰（VA）、火山浮石（VP）、火山凝灰岩（VT）等。考虑到这些物质的火山灰活性和力学特性，土木工程师提议将它们用作低碳/水泥和环保混凝土行业的辅助胶凝材料（SCMs）或人工/天然骨料。VRMs在混凝土中的应用已引起研究界越来越多且紧迫的关注。通过文献综述，本文全面介绍了VRMs和VRM混凝土（VRMCs）的性能，包括原始VRMs和VRMCs的物理和化学性能，以及VRMCs的新拌性能、微观结构性能和力学性能。此外，考虑到环境影响和长期性能的发展，本文还总结了VRMCs的耐久性和稳定性性能。前者关注VRMCs在遭受氯化物、硫酸盐、海水和冻融等侵蚀性环境影响时的抵抗性能。后者主要包括VRMCs的疲劳、徐变、隔热和膨胀性能。本研究将有助于促进混凝土行业的可持续性，保护自然环境，并减少火山灾害的影响。基于此综述，讨论了一些主要结论，并提供了关于未来VRMs在混凝土行业应用研究的重要建议。
