Engineering in seawater face materials corrosion such as concrete and steel bars attacked.
A range of supplementary cementing materials (SMC’s) exist including GGBS (ground granulated blast furnace slag), PFA (pulverised fuel ash) and other waste materials from industrial processes [10].
The raw materials are extracted from the quarry crushed to a very fine powder and then blended to the correct proportions [11, 12].
Because CaCl2 and Mg(OH)2 are non-gelation materials they seriously damaged the inner structure of concrete, at the same time many free chloride ions lead to the corrosion of steel.

Representation of Material Information The MEMS material attribute data has the obvious half structurized characteristic.
Moreover, non-silicon materials such as glass, quartz, ceramic, plastic and metal material are also emerging in MEMS.
The commonly used materials and the attributes in the MEMS design and manufacturing are described using XML in this section.

Introduction Lead titanate(PT) as a typical perovskite-type ferroelectric materials, has been extensively studied due to its remarkable ferroelectric, pyroelectric and piezoelectric properties and applied as high frequency piezoelectric materials such as optoelectronics, transducers, sensors and nonvolatile memories in advanced technology fields[1,2].
The research work provides the probability of the application of such materials and aid in the research work of preparation of relative films.
Materials exhibit apparent piezoelectric effect with enlarged activity of atoms in c axis and anisotropic characteristics.
Additional, the little changing of δof PMT in 0.1~1MHz aid in the development of its applications as excellent piezoelectric materials.
It is believed that the extent of single-domainization has a sever influence on the pyroelectric performance of the materials.

Introduction The ferritic stainless steels are materials of great interest in diverse areas because of their excellent combination of mechanical properties and corrosion resistance.
The crystallographic textures in the starting materials were determined by means of X-ray diffraction using a Philips X’Pert PRO MPD texture diffractometer.
