Description

The Construction Method of IN-situ Stabilized Excavated Materials ‹INSEM› by which excavated sandgravel materials are fully effectively used without wastes is introduced in Sabo works for difficult sites of treatment of the waste materials. The INSEM is a construction material to stabilize in-situ sand-gravels generated by excavation works through mixing with cement. Though the INSEM is similar in material to the CSG or soil cements, the INSEM method is fundamentally unique in its complete treatment of waste soils. The method can be applied to multi-purpose usage for whole structures, foundations, inside cores etc. by reason of its inherence such as simplicity, diversity and economy.<br>This paper mainly presents the laboratory test results on basic mechanical properties of the INSEM indispensable to using it in the right place for sabo structures. The basic properties include compressive strength, shear strength, deformability and erosion resistance peculiar to Sabo structures. The test results show that the INSEM is an useful material having the sufficient mechanical properties for Sabo structures. Using this material appropriately may be a means to attempt an optimum solution to Sabo structures adaptable to the new era.
