In this study, the effect of temperature on volume strains in three
types of local clay soils was studied after adding different percentages of
sand for each soil (10%-20%-30%40%-50%) when temperatures change
from (20-60)° C to be used as liners i
n solid waste landfill sites . The
results of the study showed that the mixing of sand with the clay played a
key role in reducing the magnitude of volume strains between (24-27%)
of the value of strains.
