| Summary: | Soft soil is one of the problematic soils with closely related to the ultimate
failure behaviour which occurs as highly compressible, poor resistance to deformation, low
permeability and also poor shear strength. UTHM soft soil sits on a very soft soil deposit
which falls in the category as described above. To construct on these soft grounds, ground
improvement as pre-treatment is necessary. For this purpose, an innovative soft soil
stabilization method using cement admixed with rubber chips was developed. This paper
reports on the effect of cement admixed with rubber chips on the undrained shear strength of
the stabilized soft soil. Disturbed clay samples were collected from the Research Centre for
Soft Soils (RECESS) based in UTHM. A series of laboratory tests were conducted to
determine the index properties of the original soft soil. The soft soil was stabilized with 5%
mixture of cement and various quantities of rubber chips, then left to cure for 7 and 14 days.
Upon curing, direct shear tests were carried out on the specimens to measure the undrained
shear strength. From the experimental results, it is shown that cement admixed with rubber
chips could significantly improve the undrained shear strength of soft soil. |
