This paper reports on the reactivity study of composite cathode materials that comprises different weight percent of La0.6Sr0.4Co0.2Fe0.8O3-α (LSCF) and BaCe0.54Zr0.36Y0.1O3-α (BCZY).
One of the materials issues governing the development of IT-SOFC that has been highlighted is the compatibility between cathode and electrolyte materials.
At calcination temperature of 1000 oC, we suggest that there were no observable chemical reactions among these two materials.

For some specifical complicated items in geotechnical engineering, make a good test model is not only very hard and have to spend much time, but also need expensive test equipment and much money for test materials.
The macroscopical failure results are not accord to homogeneous material because considered the nonhomogeneous property of material.

When cement in the cementing materials meeting the water, C3A reacts immediately, C3S and C4AF hydrate quickly, and C2S does slower.
In the fig.5, the plate-shaped and the sheet materials were CaO and Ca(OH)2, and the flocculent material is the silicate hydrate gum body C-S-H, and the rods materials were calcium alum stone AFt.
