| Summary: | This study is to explore the shear wave velocity of incineration bottom ash residue in the
environment through cyclic triaxial testing. The bender element is used to transmit and received
the S-wave which travels through the sample. Both dry and saturated test are used in the cyclic
triaxial test stage.
The results of the two samples are obtained for shear wave velocity. The results suggest that
shear wave velocity for dry test is higher than saturated test, as according to literature review
of previous tests done on saturation. The peak-to-peak values and start-to-start values were also
explored and compared, showing that both values can be used in lieu of each other.
Concurrently, the first sample of incineration bottom ash has a higher shear wave velocity
compared to the second sample of incineration bottom ash. This shows that the first sample has
higher chance of being used in construction due to its higher subgrade strength and capable to
withstand higher seismic movements. |
