The different effect of chemical activators on mechanical properties and microstructure of cement-base repair materials were investigated.
To meet the strength require of the repair cement based materials, some methods must be tried to activate the potential reactivity of natural pozzolan.
In previous literatures [6-8], it has been found that the addition of proper activators can obviously increase the strength of cement based materials.

SiC-Ti functionally graded material (FGM) was prepared by polymer-derived method in order to resolve connection problem between the ceramic matrix and its composite materials, as well as metal at high-temperature.
Gradient materials were fabricated successfully by polymer-derived method combined with hot-press sintering process at 1300℃.
Several years ago, gradient intermediate layer (as called buffer layer) materials were used to reduce the residual stress of the connecting joints and improve jointing strength [1].
The SiC-Ti graded materials have reached the gradient of the initial request, because of the obviously gradual process of elements.

The origin of the piezoelectric effect is outlined in terms of the symmetry of the materials.
Another technique is based on acoustic waves penetrating through and/or reflected by air-filled porous materials such as unconsolidated solid beads of grain[69].

Experimental investigation methods and techniques are used to obtain accurate information on the tension and deformation of materials.
Results underlying the limit stress state that aply to materials at this moment come from experiments on plain specimens and specimens showing stress concentrations.
Steel sheets are positively strain-rate sensitive materials which make distinct crosshead speeds generate different load–stroke curves even for specimens with identical shape and dimension [4].
Shear stress with mesh a) in Y-Z plane; b) detail of the area with stress concentrators The failure is going to happen perpendicular on the maximum principal stress directions, as seen in Fig. 6, which actually is the 45 degree section we considered critic and also the main minimum principal stress directions (because we have a ductile material, in case of brittle materials the failure might take place on the shortest section of the specimen).
