APPLICATION OF GRANULATED BLAST FURNACE SLAG TO THE EARTHQUAKE RESISTANT EARTH STRUCTURE AS A GEO-MATERIAL

摘要：

Granulated Blast Furnace Slag (GBFS) is expected to be useful as a liquefaction-resistant geo-material because GBFS increases in shear strength with time in the ordinary natural wet condition. In this paper, in order to clarify the cyclic shear strength of GBFS for a different stage of hardening, the static shear tests and cyclic un-drained tri-axial tests were carried out for specimens cured in the laboratory and in the field. As a result, it is observed that the cyclic shear strength increases proportionally with static shear strength and specimens with unconfined shear strength over 50kN/m2 collapse showing a tension crack on its surface in the cyclic tri-axial test.
