AbstractThe thermal conductivity of saturated remoulded Leda clay, a soil of post-glacial marine origin, increased from 5.5 to 7 B.t.u. in/sq.ft hour degrees F for an increase in dry density of 20 lb/cu.ft(75-95 lb/cu.ft) and decreased from 7 to 6 B.t.u. in/sq.ft hour degrees F for an increase of clay size particles from 39 to 60%. The undisturbed soil appeared to have a higher thermal conductivity in the direction normal to the ground surface than in the remoulded condition, but insufficient results are available on which to base conclusions. Extrapolating the thermal conductivity to 100% solids gave a value of ll.8 B.t.u. in/sq.ft hour degrees F. The use of the value for the solid fraction in De Vrie's method for predicting the conductivity gave reasonable agreement with measured results.
