2021-8-24  ABSTRACTColumn studies with two soils showed that hydraulic conductivity decreased with the addition of gypsum of particle size less than 44 micrometers but was unaffected by a particle size of 0.25 to 1.00 millimeter in diameter. The effect of lime powder on the initial hydraulic conductivity of the soils was similar to that of gypsum.
