Introduction In order to reduce the electromagnetic radiation of communication, computer and other electronic equipment as well as harm to human health, the research of absorbing material has become one of the hot research topics in materials science [1].
The current study of absorbing materials are mostly focused on military and absorbing materials for civil architecture research is relatively few, and multi-function and low cost are the key to building absorbing material application[2].
Experiments Raw Material 42.5R Portland cement, class I fly ash are the cementitious materials.

Evolution of accidentology science, computer engineering and systems of data collection and processing has allowed in recent years, development of border areas that make the connection between life sciences and engineering.
Shape memory alloys are typically functional materials, being more important what they do (take action) than by what they are (a property).
The properties that distinguish these classic materials are multiple: - resumption freely shape: memory materials resume their original shape when heated above the critical temperature after a plastic deformation property called shape memory effect simple.
The adaptive modular implants based on smart materials represent a superior solution in the osteosynthesis of the fractured bones over the conventional implants known so far.

Abstract: Indentation is a mature technique that has been widely used in materials science to investigate the mechanical properties of metals and thin films.
The indentation technique provides accurate modulus and hardness values of materials over many length scales and can target specific microstructures within heterogeneous materials.
The breaking force and toughness results determined are based on the materials overall structure and composition.
