Abstract
In this study, an attempt has been made to improve the geotechnical properties and check the suitability of fly ash for civil engineering applications like slope stability, backfill material for retaining walls, and road construction. Fly ash was reinforced with different lengths (6, 12, 24, 36, and 40 mm) of polypropylene fibers. The fibers were added 0.6% by weight of the fly ash. The various effects of fiber lengths on dry density, moisture content, angle of internal friction, cohesion, unconfined compressive strength, and California bearing ratio value were studied. It was observed that different lengths have different effects on each property. Overall observation was that the 12 mm fiber length has shown good results for angle of internal friction, maximum dry density, and 24 mm fiber length was good for unconfined compressive strength value. The CBR value was increasing for higher length.
