Replacement of Sand with Bauxite Mining Waste in Concrete ...

The quantities of sand replaced with bauxite mining waste used are 0, 25, 50, 75 and 100%. Cube, cylinder and beam specimens were molded and cured for 7, 14, 21 and 28 days, and tested for density, compressive strength, tensile splitting strength and flexural strength. The study found that there was a slight increase in density of bauxite mining waste produced concrete over the control as the ...
