MECHANICAL CHARACTERISTICS OF TATAKI, OR ARTIFICIAL STONE, MADE FROM WASTE OF SILICEOUS TUFF AS GEOMATERIALS

Abstract

this to clarify the mechanical characteristics of “Tataki”, or artificial stone, made from waste of the siliceous tuff, a series of laboratory tests are carried out. The experiments involve unconfined compression test, bending test and needle penetration test. From the experimental results, the in-situ applicability of Tataki as geomaterials or civil engineering materials is discussed. The following conclusions are obtained from the present study: (1) Unconfined compressive strength of Tataki
