Abstract

This study aimed to determine (1) the base characteristics of Bili-Bili Dam’s dredging sediment soil (2) the change of strength capacity of dredging sediment soil stabilized with cement for construction material use such as paving block, blocks(batako), ceramic roof tile and concrete roof tile. This study was conducted in laboratory by using dredging sediment samples from Bili-bili dam’s intake and taken from 12 dredging points and located around 100 – 200 m from sluice gate of the dam. Testing and data analysis used are standard methods such as ASTM, AASTHO, and SNI. The Result of study showed that the base characteristics of dredging sediment as fined grain soil (silt-clay) with PI 17,205 % by various percentage of cement addition 5%, 10%, and 20% (cement stabilized), unconfined compressive strength test with soaking time 3, 7, 14, 28 days, showed the increase of compressive strength capacity of sediment and met the condition as construction material.
