A large portion of surface layers on earth in moderate regions consist of peat which is the case in northern parts of Iran where peat layers are of considerable depth. Peat has very low strength and is highly compressible under loads and very moisture-sensitive, and thus considered problematic. As a result, stabilizing peat is the aim of many civil engineering projects. In the present experimental study, the effects of cement and sand on geomechanical properties of peat have been studied. The samples were prepared with different cement and sand contents of 5, 10 and 15% of each additive. To investigate the geomechanical effects of these additives on peat, atterberg limits tests, compaction test, unconfined compressive strength and CBR tests were performed. The results indicated a significant improvement in geotechnical properties of peat which was validated by SEM scanning of samples microstructure.
