3. INTRODUCTION
SOIL CEMENT Is compacted mixture of
soil/aggregate, Portland cement,
water. It is also known as cement
stabilization of soil or cement treated
aggregate. It is widely used as low
cost pavement base.

4. WHY SOIL CEMENT????
Failing granular-base pavements, with
or without their old bituminous mats,
can be salvaged, strengthened, and
reclaimed as soil-cement pavements.
This is an efficient, economical way of
rebuilding pavements. Since
approximately 90 percent of the
material used is already in place,
handling and hauling costs are cut to a
minimum.

5. RAW MATERIALS
Soil/aggregate
Portland cement
Water

6. TYPES OF SOIL CEMENT
Cement modified soil
Cement-treated base
Full depth reclamation

7. APPLICATIONS
Earth embankments
Pavements
Soil-cement bricks

8. PERFORAMANCE
 Soil-cement thicknesses are less than those
required for granular bases carrying the same
traffic over the same sub grade. This is
because soil-cement is a cemented, rigid
material that distributes loads over broad
areas.
 Its slab-like characteristics and beam
strength are unmatched by granular bases.
 Hard, rigid soil-cement resists cyclic cold,
rain, and spring-thaw damage. Cement
stabilizes soil in two ways. First, it reduces
soil plasticity, especially for the soil in which
there is high amount of clay particles.

9. ADVANTAGES
Reduces cost
Eliminate waste
Improve strength
Decreases volume change
characteristics
Improve performance

10. DISADVANTAGES
Can not operate if moisture of soil
above 10%.
Cracks may form in soil cement.
It is harmful for environment.
It requires extra labor.
The quantity of water must be
sufficient for hydration of cement and
making the mixture workable.

11. CONCLUSION
As a civil engineer our aim is economy
with out losing strength. Hence soil
cement is best choice for low traffic
pavements. Soil cement bricks are
ecofrinendly with nature.
