The Effect of the Use of Mono Potassium Phosphate (MKP 52+34) as a Stabilization Material on Clay Soils in Terms of the California Bearing Ratio Value and Free Compressive Strength Testing

Introduction

Land plays a vital role in every construction project, especially in Indonesia, which has a diverse range of soil conditions. In many cases, the soil lacks adequate technical properties, such as compressibility, permeability, and plasticity, which can affect its carrying capacity. Therefore, soil stabilization is a necessity to improve the quality of the soil that is not good. In this study, Mono Potassium Phosphate (MKP 52+34) was used as an additional material for the process of stabilizing clay soil.

The Importance of Soil Stabilization

Soil stabilization is a crucial process in construction projects, especially in areas with poor soil conditions. The primary goal of soil stabilization is to improve the technical properties of the soil, such as compressibility, permeability, and plasticity, which can affect its carrying capacity. By stabilizing the soil, engineers and construction workers can ensure that the foundation of the structure is strong and stable, reducing the risk of structural damage in the future.

The Role of Mono Potassium Phosphate (MKP) in Soil Stabilization

Mono Potassium Phosphate (MKP) is a chemical compound that has been widely used as a soil stabilizer. MKP is known to improve soil stability by reducing water content and increasing soil cohesion. This is particularly important in clay soils, which have a tendency to shrink and expand. By adding MKP to the soil, engineers and construction workers can improve the physical and mechanical properties of the soil, making it more suitable for construction projects.

The California Bearing Ratio (CBR) Value and Free Compressive Strength Testing

The California Bearing Ratio (CBR) value and free compressive strength testing are two important tests used to evaluate the stability of soil. The CBR value is a measure of the soil's ability to support loads, while the free compressive strength testing is a measure of the soil's ability to resist deformation under load. In this study, the CBR value and free compressive strength testing were used to evaluate the effect of MKP on the stability of clay soils.

Methodology

In this study, a total of 15% mixture variation of MKP was used to stabilize the clay soil. The CBR value and free compressive strength testing were conducted on the original soil and the soil treated with MKP. The results of the tests were then compared to evaluate the effect of MKP on the stability of the soil.

Results

The results of the study showed that the CBR value of the original soil was 6.29%, while the CBR value of the soil treated with MKP was 10.87%. The free compressive strength testing results showed that the original soil had a compressive strength of 1.42 kg/cm², while the soil treated with MKP had a compressive strength of 3.10 kg/cm². These results indicate that the use of MKP as a soil stabilizer can improve the stability of clay soils.

Discussion

The results of this study demonstrate the effectiveness of MKP as a soil stabilizer. The improvement in the CBR value and free compressive strength testing results indicates that the use of MKP can improve the stability of clay soils. This is particularly important in areas with poor soil conditions, where the use of MKP can help to improve the technical properties of the soil.

Conclusion

In conclusion, this study demonstrates the effectiveness of Mono Potassium Phosphate (MKP) as a soil stabilizer. The improvement in the CBR value and free compressive strength testing results indicates that the use of MKP can improve the stability of clay soils. This is particularly important in areas with poor soil conditions, where the use of MKP can help to improve the technical properties of the soil.

Additional Analysis and Explanation

The use of additional materials such as Mono Potassium Phosphate (MKP) in the process of stabilization of clay soil is very relevant, given the physical and mechanical properties of the soil that can be improved by adding these chemicals. MKP is known to improve soil stability by reducing water content and increasing soil cohesion. This is very important, especially in clay soils that have a tendency to shrink and expand.

The process of stabilization not only helps in increasing CBR and UCT values, but also has a positive impact on the nature of soil plasticity. With the decrease in the value of plasticity, clay soils will be more easily managed in the construction process, which in turn can reduce the risk of structural damage in the future.

In addition, the results obtained from the test show that the existence of the MKP can optimize the function of clay soil as a foundation. This is very useful, especially in the context of infrastructure development that requires strong and stable material. By understanding the effect and benefits of using the MKP, engineers and construction workers can make better decisions in the selection of materials and construction techniques used.

In order to achieve better quality construction, it is important for professionals in the field of geotechnics to continue to conduct further research and experiments about the use of other chemicals that can function as soil stabilizers. That way, it is expected that the strength and carrying capacity of land in Indonesia can continue to increase and in accordance with the expected standards in infrastructure development.

Recommendations

Based on the results of this study, the following recommendations are made:

The use of Mono Potassium Phosphate (MKP) as a soil stabilizer can be recommended for use in areas with poor soil conditions.
Further research and experiments should be conducted to evaluate the effectiveness of other chemicals as soil stabilizers.
The use of MKP as a soil stabilizer can be recommended for use in infrastructure development projects that require strong and stable material.

Limitations of the Study

This study has several limitations, including:

The study was conducted on a limited number of samples, which may not be representative of all clay soils.
The study only evaluated the effect of MKP on the CBR value and free compressive strength testing results, and did not evaluate other properties of the soil.
The study did not evaluate the long-term effects of using MKP as a soil stabilizer.

Future Research Directions

Future research should focus on evaluating the effectiveness of other chemicals as soil stabilizers, as well as evaluating the long-term effects of using MKP as a soil stabilizer. Additionally, further research should be conducted to evaluate the effect of MKP on other properties of the soil, such as permeability and plasticity.
