Abstract:
The study investigates the influence of
varying proportion of Ordinary Portland Cement
(OPC) in high plastic clay soil while soil-cement
stabilization of road embankment. Since, high plastic
clay is unsuitable as subbase material of road
embankment, our study provided as a guideline for the
mixing ratios of OPC in soil-cement stabilization in this
regard. Unconfined compressive strength (UCS) of soil
samples were increased significantly with the addition of
OPC to the soil. Optimum moisture content increased
with higher percentage of cement added to soil. Besides,
UCS of soil-cement mixture were improved with the
increase of curing period. On contrary, increasing
%OPC in soil-cement stabilization is costly. The test
results recommended that the addition of 10% cement
was sufficient enough to gain adequate UCS within 1-
day curing.
