Assessment of Bearing Capacity and Settlement Characteristics of Organic Soil Reinforced by Crushed Concrete and Sodium Silicate Columns

Organic soil has a high content of water and compressibility. This paper sheds light on organic improving its shear resistance through the use stone columns to strengthen reduce precipitation. Four crushed concrete were used after mixing them with 9% sodium silicate, this ratio was chosen several laboratory tests determine ideal ratio. The curing period gives highest compressive strength for mixed silicate. experiment conducted times untreated soil, then treated loamy columns, it showed an improvement rate 423% compared unimproved soil. Then, based base used. reached 700% considering same test conditions percentage in addition using similar diameters lengths columns.
