| Abstract | Seventeen representative block samples were collected from
the Mae Salid Site of Tak province, Northein Thailand . Detailed
study of the engineering properties of the Tak diorite were
conducted in the laboratory. The water content of the Tak diorite
is 0.11%, while the water absorption is 0.22%. The dry density of
the Tak diorite is 2.86 g/cc . The porosity and the void index are
0.62% a nd 0.!~ · The coefficient of the linear thermal expansion
is 6 . 94 x 10 /°C . The Tak diorite is medium to coarse-grained ,
homogeneous , intermediate igneous rock. The uniaxial compressive
strength and the diametral point load strength index are 206 . 9
MPa and 12.4 MPa respectively. Th e former is 16.74 times the
latter. The tensile strength is 17.8 MPa and the brittleness of
the Tak diorite (oc/ot) is 11.7. The point load strength index is
0 . 7 times the tensile strength. The cohesion and the friction
angle are 33 . 01 MPa and 54.5°. The P-wave and S-wave velocity are
6166 m/sec and 3466 m/sec respectively . Th e Schmidt hammer
hardness value is 66.4 for core samples and 63.9 for block
samples. The wear percent and the uniformity factor of the Tak
diorite are 16 .45% and 0 .25 respectively. The correlation between
various mechanic a l properties were made. Th e value of the
diametral point load strength index and the Schmidt hammer
hardness value can be used as index properties for the Tak
diorite. The results s how that the Tak diorite can be classified
as very high strength with average modulus ratio (AM ) . |
