It has been unusual to utilize foamed cement (FC) for embankment fill materials, which has been conventionally used as a matrix of lightweight concrete. The FC reported by this paper was produced with the porosity n=80-90% for the purpose of using as lightweight fill materials because of its dry unit weight γ_d≈0.3gf/cm³. To mke clear mechanical properties of FC, unconfined compression tests and tri axial compression tests were performed. This paper describes about these results, which are summarized as follows. (1) Unconfined compressive strength of FC firmly correlate with void ratio and water content after curing. (2) Compressive yield stress is inversely proportional to effective confining pressure.
