with peat. The addition of sodium silicate to peat at effective dosage yields a substantial
increase in the undrained shear strength.
7.9.2 Cement and silica fume stabilized precast columns
Kalantari
et al.
(2012) have used precast cement stabilized peat columns, with and
without the addition of silica fume to study the compressibility behaviour of peat.
Plate load tests were also conducted to study the bearing capacity of precast stabilized
peat columns.
The compression (
