  • Red mud is an inorganic by-product produced from the mineral processing of alumina from Bauxite ores. This study is to investigate characteristic with respect to curing conditions according to the red mud content. The results best of best showed that the water curing compressive strength better than atmospheric curing, steam curing.

  • The several monoazo red dyes having different alkyl substituents were synthesized to dye unmodified polypropylene fiber. The affinity of the dyes onto unmodified polypropylene was increased with the increase of the length of alkyl substituents. Therefore, the hexyl-substituted dye having the longest alkyl group in this experiment showed very high color strength of dyeings with K/S value of over 28 at maximum adsorption wavelength. The color fastnesses of washing, light, rubbing and sublimation were also improved significantly for the longer alkyl substituted dyes.
