Abstract


This research aims to determine the compressive strength and shear strength on clay which is
substituted with a mixture of sand variations. Soil tested in this study is derived from clay of
Belimbing Sari Village, Jabung District, East Lampung. This is done because if you set up a
structure on top of the clay will cause some problems, among others, the small value of
compressive strength and shear strength of the soil.
To determine the effect of mixing clay with sand on the compressive strength and shear strength, it
is done by varying the mixing of sand by 10%, 20%, 30%, 40%. From the test results it is obtained
that the increase in shear strength to a maximum of 0.7534 kg / cm2 and a decrease in cohesion
value of 0.10 kg / cm2 at mixing the sand as much as 40%. In the compressive strength reaches a
maximum value at 30% of the mixing done 4 variation is equal to 0.4996 kg / cm3. The greater the
level of sand were added then the lesser the value of the soil cohesion, friction angle and the
compressive strength will increase although the maximum compressive strength value in mixing
30% sand.
Keywords : Clay, Sand, Soil Compressive Strength, Soil Strength Press
