| Research Abstract |
This study shows new blending techniques for producing impermeable soil material for core zone, using the muddy soil deposited in the bottom of irrigation ponds, the old banking material lacking fine-grain fraction, fly ash, and granulated blast furnace slag, cement, etc. Judging from the results of unconfined compression tests and permeability tests, it was found that the new blending material can be used for core zone material sufficiently. Additionally, in an actual irrigation embankment construction site, field tests were conducted using large soil mixing machines. It was found that these large machines were useful for getting impermeable core material.
