Impact of Marble Powder and Brick Dust on Engineering Properties of Black Cotton Soil

-

The present article is based on one of my research on the soil stabilization. It is an experimental analysis of the effects of waste/by-product materials on the black cotton soil.

Materials and Methodology:

Materials:

For the consideration of environment-friendly and waste/by-product materials we selected marble powder and brick dust as a stabilizer for this project.

Marble Powder:

Marbles Powder produces from the cutting and grinding of marble stone. It is having very fine particles along with non-plastic characteristics. The use of traditional techniques to stabilize the soil faces problems like high cost, and/or environmental issues. The improvement of soil by marble dust is an alternative solution as it is a by-product material and available at very cheap rates. For the stabilization we have utilized Dolomite Powder which is a form of Marble Powder having a high degree of purity and whiteness.

Brick Dust:

Brick Dust is a waste material produced at the traditional brick production kiln. It is a fine particle material available at the place of burning after removal of the burnt bricks. It contains mix properties of clay and lime as they are used to form and produce bricks. Although having clay itself in the structure, it helps to improve the engineering properties. It is easily available at cheap rates which makes it an economical solution for stabilization.

Methodology:

  • During the project, only engineering properties were analyzed for the locally available Black cotton soil.
  • For the identification of the optimum amount of mix after studying several previous pieces of research we have selected the replacement of the soil by 30%, 40% and 50% of its weight by the stabilizers. So for the analysis of engineering properties following mix were prepared.

  1. 70% Black cotton soil & 30% Marble Powder.
  2. 60% Black cotton soil & 40% Marble Powder.
  3. 50% Black cotton soil & 50% Marble Powder.
  4. 70% Black cotton soil & 30% Brick Dust.
  5. 60% Black cotton soil & 40% Brick Dust.
  6. 50% Black cotton soil & 50% Brick Dust.

  • Following test were conducted for the analysis

  1. Grain Size Analysis (IS 2720 – PART IV - 1985)
  2. Atterberg’s  Limit (IS 2720 – PART V - 1985)
  3. Modified Proctor Test (IS 2720 – PART VII - 1983)
  4. Linear Shrinkage (IS 2720 – 20 - 1992)

Concluding Remarks:

It is identified from the results that both of the stabilizers show improvement in the engineering properties of the black cotton soil. It is advisable to use 40 or 50% of the marble powder as it shows more positive results compared to brick dust. Considering economic view 40% marble powder can apply to a small projects to maintain the project economy as in recent times marble powder is also started being used in other construction practices.

Note:

The presented data of the laboratory experiments are genuine and only available for future study for academic purpose only.

Seawater Intrusion: Introduction, Causes, Measures & Research Scope

Introduction: India is having about 7516 km long coastline around the borders. Besides considering the population of India around 25% of the population lives nearby the coastline. Moreover, coastal zones are having most of the industries over it. India has a wider eastern coast compared to the western coast which is more saline due to the presence of the Arabian sea [1] . The availability of saline water within the nearby range of habitat elevates the problem of seawater intrusion. The eastern coastal zone is having to sever the problem of intrusion where considering states Gujarat and some parts of Maharashtra are having very low intrusion problems. The amount and the reasons related to the seawater intrusion can only be found by the filed based research studies [2-10] . In simple words, violation of saline water into the fresh groundwater aquifer is considered as a seawater intrusion [11] . In the normal scenario, seawater is obstructed from entering into an aquifer due

Introduction Working on problematic soil in the field of the construction industry is a challenging part from the very beginning. A considerable land is covered with problematic soil. This challenge leads us towards the identification of its possible solution to utilize it in the industry. There are several ways to overcome this problem. One of the most ideal solutions is to improve the properties of problematic soil up to our desirable criteria. Soil Stabilization is a widely used and accepted method for the improvement of soil properties. Stabilization of soil is the process of improving or enhancing the properties using physical, chemical or non-chemical additives [1] . In other words it can also be described as a method to achieve a stable mix of the soil mass and admixture content which can improve the geotechnical properties of soil. Advantages of Stabilization Provides a working platform for the project It improves the strength

Zero Energy Building Concept: The energy sector of India has evolved and made astonishing progress over recent years. Considering electricity production and consumption, India is the third-largest producer as well as the third-largest consumer   [3] [4] . It is notable that Renewable power generation also made impressive progress which covers around 34.68% of the total capacity. The residential sector had a major impact on the consumption of energy which is about 24.76% of the total production  [5] . To minimize consumption there are many ways to achieve it. Zero Energy Building (ZEB) for the residential sector is one of the solutions to reduce the overall consumption of energy. In simple words, ZEB is the building using renewable technologies to meet the energy demand balancing the total supply  [1] . The concept of ZEB is using the terms at which a building is utilizing the locally available renewable resources to produce the electricity where the total produced energy a
