The effectivity of the SBF test is based on the similarity of the thin amorphous calcium phosphate layer at the living bone / bioactive material and the bone-like apatite sub-microcrystals overgrown on the material in SBF.
Materials and Methods Powder of HAp was prepared by a precipitation synthesis from calcium hydroxide aqueous suspension and phosphoric acid at room temperature (RT) [5].

Though the bend section of connectors is detrimental to the setting of transverse steels in reinforcement, the disadvantage could be overcome by reasonable design.At the same time, serpiginous bars connectors could be directly made by reinforcement( as shown in Figure 2 or Figure3 )that is not less than 10 mm in diameter(both gradeⅠand gradeⅡare okay), which has the advantages of convenient employ and using local materials, as well as with no use of special equipment and tipped tools, last but not least, they are convenient to weld and could do without machining and cutting.
Serpiginous bars connectors can make a bend bar form a “truss” in the concrete flange to change the “cantilever” status of a stud, and hence increase stiffness and reduce slip; in addition, serpiginous bars connectors can act as longitudinal reinforcement in the steel-concrete flange, in other words, no additional longitudinal reinforcement is needed, working time and materials are saved to a large extents.

Thus, it has become an important supplement to concrete, steel and other traditional materials [4].
FRP-reinforced concrete structure is a kind of structural member with high durability, which makes use of a few FRP materials as the shell of the structure, so as to prevent external corrosion to internal reinforced concrete structure.

From the obtained results there is not drastic difference in the crystalline phases between the obtained materials Dt-100 and Dt-300.
Recently, there are many interests in adsorption processes using low cost and available materials for dyes removal.
Materials and methods.
The material obtained was noted Dt-100.
This study has allowed us to show that it is possible to substitute existing high cost adsorbent materials (like activated carbon) by effective and low cost ones.

At the same time, due to the high current density on the spot, the local temperature may be high, which makes a strong evaporation of the welding wire material and the metal vapor emit from the spot at certain speed.
