Chloride Ingress Resistant Concrete: High Performance Concrete Containing Supplementary Composites

1 Associate Professor of Structural Engineering College of Engineering, King Saud University Email: [email protected] Abstract – In Reinforced concrete structures chloride ion penetration is considered to be a major cause of corrosion of reinforcing bars. Conventional concretes fail to prevent the intrusion of moisture and aggressive ions adequately. The use supplementary cementing composite ma...

Preliminary Analysis of Red Mud Spill Based on Aerial Imagery

One of the largest industrial spills in Europe occurred in the village of Kolontár (Hungary) on October 4, 2010. The primary objective of the hyperspectral remote sensing mission was to monitor that is necessary in order to estimate the environmental damage, the precise size of the polluted area, the rating of substance concentration in the mud, and the overall condition of the flooded district...

Chloride Resistance of Concrete

The color removal of dye wastewater by magnesium chloride/red mud (MRM) from aqueous solution.

In this study, the MgCl2/red mud system (MRM) was used to investigate the color removal efficiency of dye solutions. Parameters such as the effect of the dosage of red mud (RM) and MgCl2 have been studied. The effect of pH on the conversion rate of Mg2+ has also been studied. The color removal efficiency of MRM was compared with that of PAC/RM and PAC/NaOH. Meanwhile, the color removal efficien...
