In the replacement mix, natural river sand was partially replaced with steel mill scale by weight basis. Due to the high-water absorption of the steel mill scale, it was used in surface-saturated dry conditions. Trail mixes performed up to 30 % replacement of sand and observed that 30% replacement was not giving good strength and workability.
