Volcano-related materials in concretes: a comprehensive review

Area of Science:

• Materials Science
• Civil Engineering
• Environmental Science

Background:

• Volcano-related materials (VRMs), including volcanic ash (VA), pumice (VP), and tuff (VT), pose environmental and health challenges.
• Their pozzolanic and mechanical properties make them suitable for use in concrete as supplementary cementitious materials (SCMs) or aggregates.
• The sustainable utilization of VRMs in concrete is a growing area of research interest.

Purpose of the Study:

• To comprehensively review the properties of VRMs and VRM concretes (VRMCs).
• To summarize the fresh, microstructural, mechanical, durability, and long-term stability properties of VRMCs.
• To provide recommendations for future research on VRM applications in concrete.

Main Methods:

• Literature review of existing studies on VRMs and VRMCs.
• Analysis of physical, chemical, fresh, microstructural, mechanical, durability, and stability properties.
• Synthesis of findings to identify research gaps and future directions.

Main Results:

• VRMs exhibit diverse physical and chemical properties suitable for concrete applications.
• VRMCs demonstrate promising fresh, microstructural, and mechanical characteristics.
• VRMCs show potential for good durability and long-term stability under various environmental conditions.

Conclusions:

• VRMs offer a sustainable alternative for SCMs in concrete production.
• Further research is needed to optimize VRM utilization and fully understand long-term performance.
• The application of VRMs in concrete can enhance sustainability and mitigate volcano disaster impacts.
