This study suggests utilizing banana fiber (BF) and lime (L) as additives to improve the clay soil (S) properties from Pasighat, East Siang district, Arunachal Pradesh. When clay soil interacts with water, it undergoes volumetric changes due to its cyclic swell–shrink behavior, which often leads to foundational and subgrade failures. In this research, 15 sets of soil samples were formulated by blending clay soil with varying levels of BF (0.3, 0.5, and 1% based on dry soil weight) and L (3, 5, and 7% based on dry soil weight). Subsequently, laboratory tests were carried out to examine the properties of these soil samples. These tests included compaction tests, which provided values for the maximum dry density (MDD) and the optimum moisture content (OMC) of the stabilized soil samples. Additionally, unconfined compressive strength (UCS) tests were conducted to assess the effects of banana fiber and lime stabilization at various curing periods: 0, 7, 14, and 28 days. The optimal result occurred with an admixture blend of S + 1%BF + 7%L. After incorporating 1% BF and 7% L into the soil and allowing it to cure for 28 days, the soil reached its highest unconfined compressive strength (UCS) at 267.34 kPa. These findings imply that utilizing BF and L is a cost-effective means of enhancing clayey subgrades.

摘要

This study suggests utilizing banana fiber (BF) and lime (L) as additives to improve the clay soil (S) properties from Pasighat, East Siang district, Arunachal Pradesh. When clay soil interacts with water, it undergoes volumetric changes due to its cyclic swell–shrink behavior, which often leads to foundational and subgrade failures. In this research, 15 sets of soil samples were formulated by blending clay soil with varying levels of BF (0.3, 0.5, and 1% based on dry soil weight) and L (3, 5, and 7% based on dry soil weight). Subsequently, laboratory tests were carried out to examine the properties of these soil samples. These tests included compaction tests, which provided values for the maximum dry density (MDD) and the optimum moisture content (OMC) of the stabilized soil samples. Additionally, unconfined compressive strength (UCS) tests were conducted to assess the effects of banana fiber and lime stabilization at various curing periods: 0, 7, 14, and 28 days. The optimal result occurred with an admixture blend of S + 1%BF + 7%L. After incorporating 1% BF and 7% L into the soil and allowing it to cure for 28 days, the soil reached its highest unconfined compressive strength (UCS) at 267.34 kPa. These findings imply that utilizing BF and L is a cost-effective means of enhancing clayey subgrades.
