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.
