Soil and geosynthetic fibre: Unconfined compressive strength test
MetadataShow full item record
Composite soils have been widely used in civil engineering applications, especially in slopes, embankment dam and landfills. This paper aims to investigate effect of fibre inclusion on Unconfined Compressive Strength of composite soil (i.e., clay composite). A series of laboratory Unconfined Compression tests carried out to evaluate fibre effect on strength behavior of composite clay. Kaolin clay was selected as soil part of the composite and plastic fibre was used as reinforcement. The fibre parameters differed from one test to another, as fibre length were changed from 10 mm to 30 mm and fibre content were selected as 1% to 3%. For each test, stress strain graph derived and the results were compared. The results proved that inclusion of fibre affected strength behaviour of clay composite so that increasing in fibre content and length caused increasing in Unconfined Compressive Strength (UCS).
