Compression Index and Small Strain Stiffness of Six Coal Bottom Ashes in South Korea
Abstract This study investigates the small strain stiffness (Gmax) of six coal bottom ashes in South Korea. One-dimensional compression tests using an instrumented oedometer cell were performed to measure the shear wave velocity (Vs), and the compression indices (Cc) of the six different bottom ashe...

| 520 | |a Abstract This study investigates the small strain stiffness (Gmax) of six coal bottom ashes in South Korea. One-dimensional compression tests using an instrumented oedometer cell were performed to measure the shear wave velocity (Vs), and the compression indices (Cc) of the six different bottom ashes were also explored in this study. The results demonstrate that, at low confinement, the Cc of bottom ashes are comparable to that of sand under a similar void ratio. However, at high confinement, the bottom ash shows very high Cc compared to sand due to the crushability of the weak and porous bottom ash particles upon confinement. The variations of α and β, which are Vs parameters (i.e., Vs = α (σ′m/1 kPa)β), with different Cc values of the tested bottom ashes are consistent with the existing empirical relationship. The Gmax of tested bottom ashes can be adequately captured by the existing Gmax estimating formula for angular sand, indicating that the Gmax of bottom ash is highly comparable to that of sand with a similar void ratio and confining stress. | ||

One-dimensional compression tests using an instrumented oedometer cell were performed to measure the shear wave velocity (Vs), and the compression indices (Cc) of the six different bottom ashes were also explored in this study. The results demonstrate that, at low confinement, the Cc of bottom ashes are comparable to that of sand under a similar void ratio. However, at high confinement, the bottom ash shows very high Cc compared to sand due to the crushability of the weak and porous bottom ash particles upon confinement. The variations of α and β, which are Vs parameters (i.e., Vs = α (σ′m/1 kPa)β), with different Cc values of the tested bottom ashes are consistent with the existing empirical relationship. The Gmax of tested bottom ashes can be adequately captured by the existing Gmax estimating formula for angular sand, indicating that the Gmax of bottom ash is highly comparable to that of sand with a similar void ratio and confining stress.

One-dimensional compression tests using an instrumented oedometer cell were performed to measure the shear wave velocity (Vs), and the compression indices (Cc) of the six different bottom ashes were also explored in this study. The results demonstrate that, at low confinement, the Cc of bottom ashes are comparable to that of sand under a similar void ratio. However, at high confinement, the bottom ash shows very high Cc compared to sand due to the crushability of the weak and porous bottom ash particles upon confinement. The variations of α and β, which are Vs parameters (i.e., Vs = α (σ′m/1 kPa)β), with different Cc values of the tested bottom ashes are consistent with the existing empirical relationship. The Gmax of tested bottom ashes can be adequately captured by the existing Gmax estimating formula for angular sand, indicating that the Gmax of bottom ash is highly comparable to that of sand with a similar void ratio and confining stress.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Bottom ash</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Crushability</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Compression index</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Shear wave velocity</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Small strain shear stiffness</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Van Ngo, Linh</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Kim, Taeki</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Kim, Youngsang</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Lee, Changho</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">KSCE journal of civil engineering</subfield><subfield code="d">Seoul : Korean Soc. of Civil Engineers, 1997</subfield><subfield code="g">24(2020), 12 vom: 02.

Compression Index and Small Strain Stiffness of Six Coal Bottom Ashes in South Korea |
| abstract |
Abstract This study investigates the small strain stiffness (Gmax) of six coal bottom ashes in South Korea. One-dimensional compression tests using an instrumented oedometer cell were performed to measure the shear wave velocity (Vs), and the compression indices (Cc) of the six different bottom ashes were also explored in this study. The results demonstrate that, at low confinement, the Cc of bottom ashes are comparable to that of sand under a similar void ratio. However, at high confinement, the bottom ash shows very high Cc compared to sand due to the crushability of the weak and porous bottom ash particles upon confinement. The variations of α and β, which are Vs parameters (i.e., Vs = α (σ′m/1 kPa)β), with different Cc values of the tested bottom ashes are consistent with the existing empirical relationship. The Gmax of tested bottom ashes can be adequately captured by the existing Gmax estimating formula for angular sand, indicating that the Gmax of bottom ash is highly comparable to that of sand with a similar void ratio and confining stress. |
