The Effect of Cement–Sodium Silicate Grout Compounds on Void Ratio and the Coefficient of Secondary Compression of Treated Fibrous Peat



Peats have low shear strength and high deformation characteristics. Peat is a naturally occurring material that is extremely soft with a high moisture content and exists in an unconsolidated state. The conventional binders used are cementitious materials, and the introduction of a new binder, sodium silicate, with other additives gives a better output than the conventional peat treatment. This article describes a laboratory study on the effect of different compounds of cement–sodium silicate grout on void ratio and the coefficient of secondary compression of fibrous peat. It is shown that by increasing the amount of sodium silicate (within 2.5 %), cement, and kaolinite in treated peat, we were able to decrease the mentioned properties of treated peat.
