However, some researches showed that the intermediate principal stress had obvious influence on the soil materials[10,11].
As the unified strength theory[12] has taken the intermediate principal stress into account and can be applied to all kinds of materials with different behavior in tension and compression, it is widely available in many engineering field[13-16].

And meta kaolines could be adhered to the recycled aggregates with other pozzolanic materials and could close the open pores of surfaces.
Raw Materials The waste concrete sludge used in this experiment was the locally produced sludge from the recycling aggregates company.
The chemical compositions of raw materials.
Waste concrete sludge was used as cementing materials and the cement mortar specimens were prepared by ASTM C109.

Damages in the material of blade in large wind turbine will cause strain and thus can produce acoustic emission.
However, fatigue process of GPR blade is different from general metal materials, GPR blade fatigue damage began in local point of resin and fiber interface, micro cracks within material cause some fiber breakage which expanded to adjacent interface [4].
The subjects of test are material of real wind turbine, manufactured into plate-type scale model.
