The characteristics of raw materials are given in Table 1.
Particle size distribution of the individual raw materials is shown in Fig. 1 Fig. 1 Particle size distribution of raw materials In order to assess the effect of the mixture modification with secondary raw materials on the consistency of the sludge, it is necessary to determine the water absorption of individual raw materials.
Fig. 2 Water absorption of raw materials The results clearly show that FBC fly ash and FBC bottom ash are of high absorption compared to other materials.

Damping of geo-materials in resonant column test is commonly evaluated with two alternative experimental methods; during a steady-state vibration (SSV) and during free-vibration decay (FVD).
In the second part, the materials and experimental techniques of the study are described briefly and the background of determining material damping in a resonant column test is also presented along with the analytical formulae.
Introduction Stiffness (G) and damping (Ds) are important properties in order to capture the complete dynamic behavior of geo-materials.
Equipment, Materials and Methods A crushed rock of hard sub-angular to angular particles was tested in the study.

Several studies [2, 3, 5-8, 13] demonstrated that the inherent problem in conventional drilling (CD) of composite materials is delamination.
Several researchers studied [3, 5, 7] the mechanism of such damage in composite materials.
An ultrasonic softening effect, which was observed in tensile tests of materials [14], may also contribute to force reductions.
It had been widely reported [11, 16] that under the influence of ultrasonic vibrations, a brittle-to-ductile transition is observed to occur in materials.

Therefore, mechanical characterization of bulk materials has attracted a lot of research.However, due to the size limitations, the traditional methods have been unable to meet the mechanical properties of these materials testing needs.

Coal waste paste materials hydration 8h generate more AFt (ettringite), and it’s the main reason of materials have a high early strength.
Flake and prismatic materials are increase gradually in hydration products after coal waste paste materials hydration 3d.
