PREFACE Dear Distinguished Delegates and Guests, The Organizing Committee warmly welcomes our distinguished delegates and guests to 2012 International Conference on Civil Engineering and Materials (ICCEM 2012) held during July 7-8, 2012 in Paris, France.
The conferences together report the results of research efforts in a broad range of Civil Engineering and Materials.
The main conference themes and tracks are Civil Engineering and Materials.
Both inward research; core areas of Civil Engineering and Materials and outward research; multi-disciplinary, inter-disciplinary, and applications will be covered during these events.

At an age of 28 days these mortars reached strengths greater than 2.5 MPa which, from a mechanical standpoint, allows for the production of non-structural elements for civil construction like sealing blocks, side walls or finish mortars.
Since these materials have low density (between 230 and 365 kg/m3), they have the potential for use as lightweight aggregates in civil construction [2].
Conclusions The compressive strength results showed the technical feasibility of the partial use of processed PU/EVA waste as lightweight aggregate in the production of non-structural elements for civil construction.
According to the results, we can verify the technical and functional viability of the technique of processing and reusing PU and EVA waste in civil construction products through mechanical recycling (in particular, milling and extrusion), as an environmental alternative in obtaining lightweight aggregates for the civil construction industry.

More and more advanced composite materials are used in mainly supporting structure of civil aviation; its airworthiness safety should be the focus of the research.
Introduction Composite has been used in civil aviation widely; the proportion of composite used in B787 structure has reached to 50%, including carbon fiber laminate, sandwich panel, GFRP and CFRP.
Advanced composite have different damage modes for its designability, engineer could evaluate the damage by finite element method, to find the maximum stress area and select the proper repair method.

As an effective detection method of stress distribution, the dynamic photoelasticity has been wide used in stress analysis, such as detection of mechanical structure, civil engineering and water conservancy etc.
Research stress wave propagation in different interface has an important reference value for engineering structure design and construction.
This method is regarded as a kind of important optical measurement method being  wide used in machinery structure, civil engineering, water conservancy and other aspects of stress testing and analysis because it has the advantages of full field, non-contact, high accuracy, high sensitivity, strong intuitive and reliability in dispose stress concentration problem [6-9] .
These results for engineering structure to prevent shock load design provide a reliable experimental basis.
