This document discusses soil cement, which is a compacted mixture of soil/aggregate, Portland cement, and water. It is used as a low-cost pavement base material. The document outlines the raw materials, types, applications, performance advantages and disadvantages of soil cement. Some key points are that soil cement can strengthen failing granular base pavements in an efficient and economical way, and that it distributes loads well and resists damage from weather due to its rigid characteristics. However, it requires proper moisture levels and can crack over time.

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.
