被撤回的出版物: Assessment of the effects of Fe2O3 nanoparticles on water permeability, workability, and setting time of concrete (Retracted article. See vol. 29, pg. 202, 2020)

The purpose of this study is to investigate the percentage of water absorption, velocity of water absorption, coefficient of water absorption, workability, and setting time of binary blended concrete with partial replacement of cement by 0.5, 1.0, 1.5, and 2.0 wt.% of Fe2O3 nanoparticles. The results showed that using Fe2O3 nanoparticles up to maximum replacement of 2.0% produces concrete with improved resistant to water permeability. Fe2O3 nanoparticles can improve the filler effect and also the high pozzolanic action of fine particles increases substantially the quantity of C-F-H gel. If this phenomenon joints with low water-to-cement ratio, it can improve the microstructure in the interfacial transition zones and thus the value of C-F-H gel results in decreasing the water permeability. The results also show that the workability and setting time of fresh concrete were decreased by increasing the content of Fe2O3 nanoparticles.
