[Audio] Research conducted by Amrutha. S C7A looked into the secondary consolidation of peat soil. Having the ability to cause substantial settling and structural harm to buildings and infrastructure, leading to expensive repairs or measures of avoiding said damages, the research demonstrated that secondary consolidation of peat soil could be managed with the use of biopolymers, which would then reduce costs..

[Audio] Peat soil secondary consolidation is the study of the deformation of soil caused by the application of a load and the changes over time in response. The degree of secondary consolidation in peat soil is determined by organic content, water content variations, fiber structure, and processes that happen over time, as well as the history of loading on the soil. In order to accurately predict how peat soil will behave in the long-term under different loading conditions, it is essential to have a good understanding of all these factors..

The outcomes generated were greatly useful and enabled us to comprehend how the incorporation of biopolymers impacts peat consolidation. This assessment provides us with an understanding of how peat can be used in various methods with the assistance of biopolymers..

[Audio] Research by Amrutha found that the pre consolidation pressure of Kunming peat had a compression coefficient between 5.7 and 8.8 MPa-1, which is well above the lower limit of 0.5 MPa-1 for high compressibility soil. This shows that Kunming peat is indeed a high compressibility soil. Moreover, the ln(1+e)-lg p double logarithmic method was employed to calculate the pre consolidation pressure successfully..

[Audio] Research conducted by Amrutha. S C7A investigates secondary consolidation of untreated and biopolymer-treated peat and its results demonstrate remarkable enhancement in strength. This is particularly obvious when focusing on the outcome of the biopolymer solution, which was observable to boost the sturdiness of the peat by almost 500%. As untreated peat is often fragile, these results demonstrate that biopolymers can significantly raise its stability and strength. This could possibly pave the way for various potential uses in civil engineering..

[Audio] The research of C7A provides an in-depth analysis of secondary consolidation of peat soil treated with biopolymers. By using the Casagrande method, the compression curve of the peat soil is observed to be inversely S-shaped under consolidation pressure, with the end of the primary consolidation pressure point and secondary consolidation coefficient being determined. Results revealed that from 25 to 200kPa, the completion time for main consolidation progresses gradually. When pressure surpasses 200kPa, the completion time for main consolidation does not increase but instead, reduces marginally, reflecting the soil's structural collapse..

[Audio] Amrutha. S C7A conducted a study on the secondary consolidation of peat, both untreated and treated with biopolymers. It was observed that Cα/Cc value of the peat soil in Kunming, China was 0.052, which is higher than other non-organic soft soils in the country. The results of this study demonstrate that biopolymers can successfully improve the consolidation of peat soil..

[Audio] Amrutha. S C7A has conducted a significant case study demonstrating that the secondary consolidation coefficient of peat soil in Kunming is between 0.9%-2.5%. This information is critical in order to comprehend the behavior of peat soil when subject to pressure and treated with biopolymers. Being aware of the specific consolidation coefficient enables us to make accurate predictions and take decisions prudently when working with peat soil..

[Audio] The case study investigated the secondary consolidation of peat soils in Kunming. Results revealed that the secondary consolidation coefficient reaches a maximum of 2.48% when the pressure is 200kPa, and then lowers to 1.63% when pressure reaches 800kPa. This implies that higher consolidation pressure is beneficial for the peat soils..

[Audio] I am here to present the findings of Amrutha.S C7A research on secondary consolidation in peat soil. This research aimed to study consolidation behavior of peat soil, both untreated and treated with biopolymers. The results showed that peakvalue of Cα in peat soil is higher than that of normal undisturbedsoft clay, ranging from 0.04 to 0.12, and is not in pre consolidation pressure but in the later 200kPa. Based on the classification standard of soil based on the εα of secondary compression coefficient, it was deduced that Kunming peat soil belongs to high secondary compressibility soil. I hope this research helps us gain a better understanding of peat soil and its consolidation behavior..

[Audio] Amrutha. S C7A has conducted research studying secondary consolidation in peat, both untreated and treated with biopolymers, in order to better understand the stabilization of peat soils. Conventional methods like surcharge loading, prefabricated vertical drains, and electroosmotic treatments have failed to be effective when treating soils with high organic content. However, dynamic replacement and mixing techniques have been developed to create a stiffer dual-layer of soil deposition, which significantly reduces secondary settlement. This research will improve our knowledge of how to properly stabilize peat soils..

[Audio] Research conducted by C7A is analyzing the secondary consolidation of peat, a type of organic soil, when it is left untreated or treated with biopolymers. Biopolymers are an effective, cost-efficient and sustainable way to improve the shear strength and compressibility of organic soils. Previous studies have already shown the effectiveness of biopolymers in this respect..

[Audio] Amrutha. S C7A is studying the secondary consolidation of peat soil, both untreated and treated with biopolymers. Biopolymer stabilization increases the load-bearing capacity of the soil. The biopolymers bind to the particles of the soil, forming a stable structure which prevents amassing and thus decreases settling. If this is applied in engineering projects, they will benefit from increased stability and cost effectiveness in the long run..

[Audio] Research conducted by C7A has revealed the potential benefits of biopolymer stabilization for secondary consolidation in peat. This technique is both environmentally friendly and efficient in enhancing soil properties, making it a cost-effective way to tackle the issue of secondary consolidation in peat.

[Audio] Biopolymers use is gaining popularity as a means of treating peat soils. Amrutha S C7A's research presented how biopolymers can have a profound influence on the secondary consolidation of peat soil, further increasing its strength, stability, and lessening its compressibility. This can result in a significantly reduced rate of secondary consolidation when compared to soil that has not been treated with biopolymers. All evidence suggests that biopolymers are an effective tool for soil treatment, specifically for peat soils as they are able to mitigate the damaging effects of secondary consolidation..

[Audio] Amrutha S C7A's research identified two primary advantages of utilizing biopolymers to treat peat soil - one, the hydrophilic properties of certain biopolymers result in increased water retention thereby guarding against extreme consolidation; and two, biopolymers upgrade soil structure, building a more steady matrix and curtailing the rate of secondary consolidation..

[Audio] The research study presented by Amrutha. S C7A examines the secondary consolidation in peat soils in its untreated and treated states. Results suggest that biopolymers in the soil matrix can reduce the rate of secondary consolidation, blocking the re-organization of particles to create a stabilizing effect. Thus, it is apparent that biopolymers can be used to reduce the effects of secondary consolidation and thus should be integrated into soil management practices..

[Audio] Peat, a type of organic soil, presents difficulties in construction projects due to its low shear strength, high compressibility, and high water content. Amrutha. S C7A is investigating secondary consolidation in peat, both untreated and treated with biopolymers like xanthan gum. Biopolymers may provide an alternative to chemical and mechanical stabilization methods, potentially reducing engineering costs, construction time, and improving foundation performance. Although further research is necessary to fully understand the potential of biopolymer stabilization of organic soils, the results of Amrutha. S C7A's work could lead to an innovative solution to the difficulties posed by such soils..

[Audio] Amrutha. S C7A's research examines the secondary consolidation of peat soil that was untreated and treated with biopolymers. This is substantiated by Abdulameer et al. 2019, Latifi et al. 2017, and Latifi et al. 2016, which discuss the use of biopolymers as an additive for stabilization of organic peat. This research has significant implications in the development of biopolymers as an effective soil engineering tool..

[Audio] The research of Li et al and Rasheed and Moghal both suggest that biopolymers can improve the secondary consolidation properties of peat soils. Such an improvement could be beneficial in places where peat soils are used, such as low-lying coastal regions and wetlands. Overall, the findings of these studies have the potential to have a major impact in the fields of civil engineering and infrastructure..
