INTRODUCTION
Soil cement is frequently used as a construction
material for pipe bedding, slope protection, and road
construction as a sub base layer reinforcing and
protecting the sub grade.
It has good compressive and shear strength, but is
brittle and has low tensile strength, so it is prone to
forming cracks.

WHAT IS SOIL CEMENT?
Soil cementis a construction material, a mix of
pulverized natural soilwith small amount of portland
cementand water, usually processed in a tumble,
compacted to high density.
Hard, semi-rigid durable material is formed by
hydration of the cementparticles.

RAW MATERIALS
Soil aggregate
Portland cement
water

Soil Cement Construction
Process steps
1. Soil preparation: Remove vegetation and debris, and grade the
soil to the desired elevation and compaction level
2. Cement application: Apply cement to the soil as a dry powder
or slurry
3. Mixing: Mix the soil and cement using a rotary mixer, pug mill, or
traveling mixing plant
4.Compaction: Compact the mixture using a roller, plate
compactor, or vibrating compactor
5.Curing: Allow the mixture to cure to achieve maximum strength

Objective of the Work
To study about soil cement roads.
To study about construction methods.
Discuss about various properties of soil cement roads.
Discuss about advantages and disadvantages of soil
cement roads.

Soil Cement Road
Soil-cement is a highly
compacted mixture of
soil/aggregate, Portland
cement, and water.
Soil-cement differs from
Portland cement concrete
pavements in several
respects.

Performance of Soil Cement
Significantly reduced thickness
soil-cement is a cemented, rigid material
Facilitates the distribution of loads over a larger area
Hard
rigid soil-cement resists cyclic cold, rain, and spring-
thaw damage.

Types of soil cement
1.Cement-modified soils (CMS)
2.Soil-cement base (SCB)
3.Cement-treated base (CTB)
4.Acrylic copolymer (Rhino Snot)

1.Cement-modified soils (CMS):
A cement-modified soil contains relatively small proportion of
Portland cement.
result :
caked or slightly hardened material
similar to a soil
but with improved mechanical properties -lower plasticity
increased bearing ratio and shearing strength
and decreased volume change

2.Soil-cement base (SCB)
A soil-cement base contains higher proportion of cement than
cement-modified soil.
It is commonly used:
as a cheap pavement base for roads
streets
parking lots
airports
material handling areas.

3.Cement-treated base (CTB)
A cement-treated base is a mix of granular soil
aggregates or aggregate material with
Portland cement and water.

4.Acrylic copolymer (Rhino Snot)
is a water soluble acrylic copolymer applied to
soil or sand which penetrates and coats the
surface.

Advantages
Environmental friendly
Low First Cost
Fast Construction
Recycling of Existing Materials
High strength and durability
Resistance to weathering and erosion
Can be used in various soil types
Low maintenance

Disadvantages
1.High initial cost
2.Requires specialized equipment and labour
3.Limited flexibility
4.Limited ductility
5.Can be prone to cracking and shrinkage

APPLICATIONS
Roads
Earth embankment
Pavements
Soil-cement blocks
Parking lots
Intrstatehighways

Benefits
Improved soil strength and stability
Increased load-bearing capacity
Enhanced erosion resistance
Reduced soil settlement and deformation
Cost-effective and sustainable

Great Strength
Cores taken from soil-cement
pavements furnish proof of its
strength. Samples taken after
15 to 20 years show
considerably greater strength
than sample taken when the
pavement was initially built.

Superior Performance
More than 70 years of collective experience have
demonstrated that different kinds of soil-cement mixtures
can be tailored to specific pavement applications,all
achieving superior performance as a result of soil-
cement’s strength.
low maintenance costs.
