セメント種類の違いがセメント安定処理土の一軸圧縮特性に及ぼす影響

抄録・要旨

This paper describes the effects of cement type on unconfined compressive characteristics of cement-stabilized soils. Two cements were used in the present study the normal portland cement and the portland blast-furnace(B) cement. Results of unconfined compression tests on stabilized soils show that the differences in unconfined compressive characteristics between cement stabilized soil utilizing normal portland cement and portland blast-furnace(B) cement tested at the same compound conditions maybe dramatic. In all tests reported herein, the unconfined compressive and deformation modulus of the cement stabilized specimen utilizing portland blast-furnace(B) cement are shown to be quantitatively greater than those of normal portland cement. These findings will lead to proper selection of the cement type for cement-stabilized soils.
