Abstract
Soft soil possess poor mechanical properties, thus produce problems when bearing load. To overcome the problems, soft soil has to be stabilised. To do soil stabilisation, it Is imperative to add some mixture as additional substance in order to improve the characteristic of the soft soil. Plastic sacks fibre is one of the easily obtainable material which consists of high density profile, while bran ash contains good carbon and silica. This research aimed to determine the optimum level of plastic sacks waste fibre and bran ash to obtain the maximum soil shear strength and to compare the original soil shear strength with the modified mixture soil shear strength. The strength tests were conducted on the laboratory scale using the triaxial test device for the Unconsolidated Undrained (UU) test. Soft clay sample was mixed with the chop of plastic sacks fibre with the following level of composition : 0.4 % , 0.6 %, 0.8 %, 1 %, and also the bran ash composition content of 0 %, 2 % and 4 % to the dry weight of soil with the test unit of 36 pieces. Based on laboratory testing, the maximum cohesion value reside on variation of 0.8 % plastic sacks fibre and 2 % bran ash with the value of 0.65 kg/cm2, and the maximum shear angle lays on variation of 1 % of plastic sacks fibre and 0 % of bran ash with the value of 9.95 degree. For the mixture variation of 0.8 % plastic sacks fibre and 2 % of bran ash, it produced a shear strength of 0.67 kg/cm2 and abled to increase the soil shear strength by 87.08 %. As a conclusion, the use of plastic sacks fibre and bran ash was found to be able to improve the soft clay shear strength properties
