Abstract
AbstractStabilization using natural fiber is an inexpensive technique to increase the properties of weak soil. Soil swell-shrinkage characteristics cause engineering problems or damage the existing structures. The effects causing damage are mainly the demolition of buildings, roads and pipelines in uncropped soils and the leaching in landfills through desiccation cracks. So a better comprehension of the desiccation cracking process is essential. This study comes out with a natural material, areca fiber. Areca is accessible adequately in so many regions all over the world, yet its application in geotechnical studies has not been investigated broadly. In this current study, the appropriateness of areca fiber in the stabilization of weak soils is shown through experimental examinations. Bottom ash (BA) is used as a stabilizing agent along with areca fiber. The tests conducted are compaction tests, unconfined compression strength (UCS) tests and a series of wetting–drying cycles. Experiments are conducted in the laboratory on the crack parameters, like crack density factor (CDF) and crack intensity factor (CIF) and characteristics of desiccation cracks on the surface of soil at different percentages of areca fibers. The image processing technique (DIA) is used to quantitatively analyze the morphology characteristics of crack patterns formed at each drying path.KeywordsDigital image analysisAreca fiberUnconfined compressive strength
