Title: The engineering properties of rice‐hull‐ash as a soil stabilizer
Abstract: Click to increase image sizeClick to decrease image size Abstract The study of an effective utilization of rice hull ash, which is produced 100,000 tons per year in Taiwan, becomes necessary. This study investigates the uses of rice hull ash with lime as a soil stabilizer admixture. The primary purposes were to study the compaction characteristics and the factors affecting the strength development of the lime‐ash stabilized sandy and clayey soils. Standard compaction test and undrained direct shear test were carried out. Results showed that adding rice hull ash into a soil increased the effectiveness of lime. Lime‐ash admixture caused the compacted dry density of a soil to decrease but the as‐compacted strength to increase. The shear strength of a lime‐ash stabilized soil increased with curing time, but reduced when soaked. The optimum lime‐ash weight ratio of soils was found to be 1:2 or 1:3. To produce equivalent strength values, the percentage of lime requirement could be reduced by adding rice hull ash.
