Hydraulic conductivity (K) is important in many tasks involving the flow of fluids through porous media, including dissolved contaminant transport and groundwater investigations. Experimental investigations concerning fly ash mixed porous media result in decreasing the K value and can be used as a barrier to different compaction characteristics. The investigation focuses on the compaction properties and K of porous media with varying quantities of fly ash content. The standard Proctor compaction test (SPCT) was performed on two different porous media with varying fly ash contents ranging from 10 to 50%. According to the SPCT, when the fly ash content increases, the maximum dry density declines, and the associated optimum moisture content increases. The optimum content of fly ash in soil samples 1 and 2 was found to be 30% and 40%, respectively, because the K value reduces uniformly. Further increases in fly ash content result in a minimal fall in K value. The obtained K values of soil–fly ash mix at optimum content lie within the domains of silt, which substantiate its use for constructing impervious embankments or groynes.
