Introduction Heat-resistant martensitic steels with 9% Cr are widely used as a structural material for the boiler and turbine components of ultra supercritical fossil power plants due to its excellent creep resistance [1,2].
It was recently demonstrated, that the creep resistance of these materials can be significantly improved by boron additives [3,4].

Expermental study on the mixture ratio and the compressive strength of concrete with Recycle crushed brick coarse Aggregate QinLiua and Xiaona Zhangb Huanghe Science&Technology College, HeNan, ZhengZhou450063, China a32090881@qq.com b45165920@qq.com Keywords: recycled coarse aggregates; concrete; mixture ratio; compressive strength Abstract: Considering the high absorption of water is a distinctive feature of recycled crushed bricks coarse aggregate, the mixture ratio text of recycled concrete using crushed bricks as coarse aggregate is carried out, and the compressive performance is studied.The resert indicate , the strength grade of recycled concrete which using bricks as coarse aggregate can reach C20 and C25, characterisitic value of cubic concrete compressive strength at the age of 28 days are 21.2MPa and 27.55MPa;Based on regression analysis of test data , the formulas which estimated the strength of recycled coarse aggregates concrete are given out.
Analysis of the reasons for the first brick, waste recycled coarse aggregate material strength is low, and the inevitable waste brick regeneration coarse aggregate in containing fine mortar, waste broken will make some recycled coarse aggregate with fine cracks, resulting in a strong degree of aggregate is low; moreover, the test of concrete test block are standard maintenance, maintenance humidity is higher than 90%, block the water loss is small, recycled aggregate "curing" performance failed to manifest.
The calculating formula of the strength of recycled aggregate concrete China's current 《mix proportion design of ordinary concrete rules》 (JGJ55-2011) provides that: value calculated by the following formula of compressive strength of concrete: (1) (2) —Test cube compressive strength of concrete of 28d age values (MPa),—Cementitious material 28d mortar strength , —the influence coefficients of fly ash and slag powder,,(In this experiment without fly ash and slag powder,so=1.0, =1.0)—Test cube compressive strength of concrete of 28d age values (MPa);—The amount of cementing material and water ratio;, The regression coefficient associated with the coarse aggregate,for the gravel ,[6]。

Advanced multifunctional biomaterials will be produced by a combination of bioaffinity of apatite with mechanical, electric, magnetic or optical properties of other materials.
Recently, we have found that when a porous insulating material is arranged between EPD electrodes, ceramic particles can be migrated by the electric field passing through the pores of the insulating material [5,6].
Then this method will contribute to development of variety of fields utilizing various properties of apatite, for instance, production of multifunctional materials having bioaffinity.
