What does this research mean for the field?

The combined application of rice husk ash and lime synergistically stabilizes silty soil for subgrade applications, increasing unconfined compressive strength by 2-6 times and California Bearing Ratio by 5-8 times compared to natural soil. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To evaluate the potential of rice husk ash and lime, applied individually and in combination, for stabilizing silty subgrade soil.

Overview

Laboratory study demonstrates enhanced strength and bearing capacity in silty soil, indicating agricultural waste effectively boosts lime stabilization.

Key Points

To evaluate the potential of rice husk ash and lime, applied individually and in combination, for stabilizing silty subgrade soil.
Treated silty soil with rice husk ash (5%, 10%, 15%, and 20% by dry weight) and lime (2.5% and 5%) alone and in combination.
Measured compaction characteristics, unconfined compressive strength, and California Bearing Ratio across different curing durations.
Adding rice husk ash and lime increased optimum water content while decreasing maximum dry unit weight.
Unconfined compressive strength increased by 2- to 6-fold compared to natural soil.
California Bearing Ratio values improved by 5- to 8-fold, demonstrating marked synergistic benefits from combined lime and rice husk ash treatments.
