Douglas HOOTON1, a * 1University of Toronto, Dept. of Civil Engineering, Toronto, Ontario, Canada M5S1A4 a hooton@civ.utoronto.ca Keywords: chloride ingress, diffusion, construction defects, cracks, performance specifications, uncertainty Abstract.
In addition to using materials and mix designs that will resist chloride ingress, construction detailing and practices have a large impact on durability.
They also often inhibit innovation since new materials and methods do not fit into the prescriptive mould.

Composite materials are formed from two or more materials producing properties that could not be obtained from any one material.
The role of the matrix material is to protect the reinforcement materials , to distribute the stress to the reinforcement material(s) , to provide for the final shape of the composite part.The role of the reinforcement material(s) is to provide the composite high mechanical properties , to reinforce the matrix in preferential directions.The properties of a composite material depend on the nature of the reinforcement and the matrix, the form of the reinforcement (particles, fibres) and the relative content of reinforcement Literature review: Hashim (1999) et al studied that combining high specific strength with good corrosion resistance, metal matrix composites (MMCs) are materials that are attractive for a large range of engineering applications.

Use of this model was important in the design of hot torsion laboratory experiments capable of reproducing some key features of the industry process.

Methods and materials In order to perform a comprehensive study of chemical registration management, and finally come to the conclusion of chemical management among economies, eight economic entities were selected with different levels of economic development, protection awareness, and management capacity.
If the item contains Substance of Very High Concern (SVHC) candidate list of substances, and the mass fraction of the material and/or output to certain requirements, enterprises need to report to the European chemicals agency and provide sufficient information [7].
However, 45000 existing chemicals have no specific regulation for controlling comparing with new chemicals have to register before production, and 84 key hazardous chemicals have to register for environmental management as summarized by Table 1.
