Comparison on micromechanical properties of interfacial transition zone in concrete with iron ore tailings or crushed gravel as aggregate

Using recycling iron ore tailings (IOTs) from industrial solid waste as concrete aggregates agrees with the sustainable development of the construction industry and carbon neutrality commitment. As the interfacial transition zone (ITZ) between IOTs and cement paste is significant to concrete performance but rarely studied, the present work is focused on the micromechanical property of ITZ in concrete with IOTs. Comparative studies were conducted...
