Jan 01, 2021 · The initial microcracks of the recycled aggregate concrete (RAC) usually first appear in the interfacial transition zone (ITZ) during the destructive process. Thus, the performance of ITZ plays an important role in the mechanical properties of concrete [7,8]. In order to improve the mechanical performance, we add iron ore tailings (IOTs) to RAC.

May 10, 2016 · As shown in Figure 3, the slumps and liquidity of concrete mixed with iron ore tailings decreased compared with that of normal concrete under the same condition (water, mixture ratio, admixture, etc.).This phenomenon arises because the particles of iron ore tailings are rough and occluded with coarse aggregate, so cohesion increases significantly in the tailing mixes.
