Popis: In order to use scallop shells of a fishery by-product effectively for the back-fill material of a quay, we are investigating the internal friction angle of the sand which mixed the crashed scallop shells by consolidated-drained tri-axial compression test. In our second report, we checked that the sand which mixed the crashed scallop shells is applicable to back-fill material. However, it turned out that how to mix sand and a shell influences unit mass and internal friction angle. This time, we investigated the internal friction angle of the mixture sand which changed the mixed method and the injevtion method of materials at making a specimen. As a result, when the maximum grain size of crashed shell is about 10mm and the rate of shell mixture is about 25%, it is thought that we can use the sand which mixed the crashed scallop shells for the back-fill material, by carrying out consolidated-drained tri-axial compression test and grain size analysis before and after compressiontest.
