Soil Cement

Soil cement is a construction material, generally, a mixture of Pulver natural soil with portland cement and water, deposited in extreme densities, soil cement has good compressive and shear strength.

Due to the hydration of cement, their particles produces hard, semi-rigid durable materials.

Here we will learn about soil cement, types of soil cement & much more.

Introduction to Soil cement:

Soil cement is also known as cement stabilization of soil or cement treated aggregates.

This cement is often used as a building material for the beds of the pipes, slope protection, and road construction to strengthen and protect the sub-base layer.

Performance of Soil Cement:

  • The thickness of this cement is less than required for granular bases that carry visitors to the same site at the same subgrade.
  • As a result, clay cement is a cemented, inflexible material that distributes loads over wide areas.
  • Their slab-like characteristics and beam strength are unmatched by granular bases.
  • They are hard, inflexible clay-cement resists cyclic freezing, rain, and spring-melting losses.
  • It reduces the plasticity of the soil, especially for soils that are excessive amounts of clay particles.

Types of soil cement:

1.Cement Modified soils (CMS):

CMS contains all the proportions of Portland cement.

The resultant clay or slightly rigid material like clay with better mechanical susceptible volume changes.

It has low plasticity bearing ratio and high shearing strength.

2.Soil cement basis (SCB):

SCB has a higher ratio of cement than the CMS.

It is commonly used as an inexpensive pavement for materials dealing with roads, roads, parking lots, airports.

3.Cement treated base (CTB):

CTB consists of a mixture of granular clay aggregates or combination materials with Portland cement and water.

4.Acrylic copolymer (Rhino snot):

In desert conditions and commercially trademarked “Rhino snot” is a water-soluble acrylic copolymer applied to soil or sand that penetrates and touches the floor.

Manufacturing procedure:

  • Before the construction begins, simple laboratory tests predict the use of cement materials, condensation and water required materials.
  • During construction, tests are done to see that the requirements are being encountered.
  • Testing ensures that the combination can have strength and long-term durability.
  • This cement can be mixed in one place or a central mixing plant; central mixing plants may be used where borrowed materials are related.

Advantages of soil cement:

1.Hardness Soil:

Cement is the basis material for a low-cost pavement, hardness, it is most needed for long-lasting parking and storage areas.

Larger paved areas should preserve their original grade and do not develop depressions or pits, if they drain freely during rain.

2.Super strength:

Higher-strength samples taken after 5 to 20 years, when the pavement construction was started.

Cement remains hydrated for some years, it has reserve strength and strong.

3.Superior performance:

Over 70 years, collective experience have demonstrated that this cement mixtures can be tailor-made for specific pavements for achieving better efficiency and strength.

Within the United States and provinces of Canada still providing good service at low maintenance prices.

Disadvantages of soil-cement:

  1. The standard needs to be strictly followed, if not it may not work correctly.
  2. Water is still capable of penetrating if capillary void on a very large scale.
  3. If the percentage of cement is too high, it is going to create a crack.
  4. Due to low ductility, the optimal percentage of cement will be 7% less than the dry soil load.
  5. It is not suitable for some type of soil.
  6. Homogeneous mixing is strictly involved, so an efficient observer or high-quality instrument is required.
  7. If soil moisture is more than 10%, it cannot work.

CONCLUSION:

The soil-cement has great benefit to both vendors and workers of commercial facilities, their cost is well-suited with the granular-base pavement.

The major engineering advantages of soil cement are strength, rigidity, improved volume stability, and increased durability.
