Abstract

Soil-cement has been widely used, as a basic material, in the foundation of many such
projects, as pavement of highways as well as lining of channels and reservoirs. This paper
presents the effect of an organic additive component (Glycerol) on the mechanical
behavior and on the properties of soil and soil-cement mixtures. Soil samples were
prepared by static compaction at maximum dry density and optimum moisture content for
various percentages of cement and Glycerol as well for various curing durations. Results
indicated that contaminated soil with Glycerol (3%, 6% and 9%) show lower compressive
strength as compared with natural soil. Furthermore the decrease in compressive strength
is seen to be a function of Glycerol percentage. In addition, the use of cement (3% and
6%) on natural soil will cause an increase in the compressive strength. Furthermore an
increase in the compressive strength of different soil-cement samples was observed to be
a function of cement percentages and curing durations. In all, soil-cement mixtures in
addition with 3% of Glycerol show greater compressive strengths as compared with
uncontaminated soil-cement mixtures. However the use of higher percentages of Glycerol
(6% and 9%) resulted in a noticeable decrease in strength as compared with
uncontaminated soil-cement mixtures.
