All materials parameters except for surface chloride content are expressed as a function of time.
This work is accomplished with the HYMOSTRUC[6], based on the knowledge of material science.[7]~[10] The diffusivity of cement paste is transformed into that of concrete using EMT theory.[11] Fig. 5 shows the calculation results.
Summary The purpose of this study is to set up a framework for defining materials parameters which can be used for durability design of marine concrete.

Flux Cored Wire Material Gas Shielded Arc Welding Thick Steel Plate Welded Crack Analysis Lianzhong Zhang, JieLi Wen The Donghai science and technology College of Zhejiang Ocean Universityboat , mountain ,Zhejiang, China,316000 Email:zlz.10001@163.com Keywords: cored wire material , gas shielded ,welded crack, analysis Abstract.The world shipbuilding industry since the beginning of the last century with flux cored wire material.Since the flux cored wire material use welding materials has developed into a more efficient submerged arc welding consumables and gas shielded welding welding consumables and can be more easily combined with automated welding and robot welding.So far, flux cored material applications favored.
From the above analysis, the cracks in the text The main reason is the high hydrogen content of the weld, sources of hydrogen welding materials, Flux cored wire and CO: shielding gas.
(2) Carbon structural steel (Q235B) excellent weldability, welding, The head cracks possibility of small, but large-scale structure in the thick products The weld, sometimes because of factors such as welding materials will crack. in accordance with the welding, CO: gas The superior grade in the body of the standard request to purchase CO gas in the actual site Production control products to the most effective method of References [1] LiangRunHua, Lin are.

Therefore, the overlapped cushioning materials are introduced.
Guo et al [14] analyzed the cushioning coefficient of overlay cushions composed of the same materials.
However, the cushioning properties of overlapped cushions composed of dissimilar materials are not focused on enough.

Carbon sink marine ecosystem model Green packaging material is not necessarily a high-tech materials, many traditional packaging material itself has the environmental material characteristics or can be developed into green packaging materials, such as recycled paper material, polylactic acid (PLA) material.
A ton of waste paper can produce good quality recycled paper 850 kilograms, saving 3 cubic meters’ wood, at the same time can water-saving 100 cubic meters, saving 300 kilograms of chemical raw materials, saving coal 12000 tons and saving 600 degree [11].
Polylactic acid ( PLA ) material can be processed into a variety of packaging materials, and PLA production energy consumption is equivalent to the traditional petrochemical product 20% - 50%, to produce carbon dioxide gas is only for the 50%, and has good biocompatibility and biodegradability.
Composite packaging materials are in difficult to reclaim.
When recycling, composite materials such as mixed with a single material will make a single material recycling quality is destroyed, resulting in waste and pollution.

Metallic materials with poor plasticity are usually difficult to get effective surface strengthening.
For low-plasticity materials, this would be an interesting discovery for SSPD technology.
