TÓM TẮT
This paper presents the experimental study results on the characteristics of unconfined and bending strenght of soil cement in sandy soil. The cement content from 150 to 350 kg per cubic meters corresponded the curing time: 7days, 14days, 21days, 28days and 56days. The correlation between unconfined compressive strenght (U.C.S), bending strength (B.S) with content of cement, curing time, alastic modulus (E50) was set. For field test, 20 test piles at two different works: 7 and 13 soil cement piles respectively are also instralled with 250kg cement per m3 sandy soil todetermine the correlation between U.C.S in the laboratory and field with wet deep cement mixing engineering using static blade. The results have important implications in the practical application of soil cement pile with hight strenght for heavy structures and high-rise building.Keywords: Sand cement pile, Unconfined compressive, Bending strenght, Sandy soil, Curing
