Abstract EN
The accelerated carbonation, natural carbonation, fast freeze-thaw test, and pore structure analysis of C30 and C50 concrete with different proportions of iron tailings powder and slag powder were tested, respectively.
The results show that the accelerated carbonation depth and natural carbonation depth of concrete increase with the increase of iron tailings powder content.
The prediction model of carbonation depth of iron tailings powder concrete is established by introducing the iron tailings content coefficient and strength influence coefficient.
The error between the calculated value of the model and the test value of 28 d curing concrete natural carbonation depth is small, which proves that the model is completely feasible.
When iron tailings powder accounts for 50% of mineral admixture, it is helpful to improve the frost resistance of concrete.
According to the pore structure analysis, the introduction of iron tailings powder can optimize the pore structure, improve the porosity of harmless and less harmful pores, and thus improve the frost resistance.
