Introduction Concrete is the most widely use scope building materials in the world,freeze-thaw damage is one of the important reason of the concrete durability.Therefore,the research on the freeze-thaw cycle of concrete has important theoretical significance,practical value and economic benefits[1].In recent years, concrete is developing in the direction of green,a lot of mineral admixtures such as slag, silica fume, fly ash, steel slag and limestone powder ,adding in concrete, has played a very good effect.So developing new cementing materials, and carries on the freeze-thaw research is imperative.
Limestone[2] is a kind of easy to get and cheap material,aggregate processing also can bring a lot of limestone powder , if we don't use them, they take up site pile and can cause pollution to the environment.In addition,along with the increase in steel production, steel slag[3] emissions are also increasing year after year, realizing the rational utilization of steel slag resources become the key of the development.If used as supplementary cementious materials, alternative increasingly scarce in the concrete and the relatively expensive silicon powder or slag,it will be of great realistic significance to environmental protection,is one of the important direction of green building materials.

Introduction Polyurethane rigid foams are popular in construction industry as thermal insulation materials.
When proportion of sepiolite nanofibers in the composite materials is more than 2%, agglomerating action increases, so the dispensability of sepiolite nanofibers in the composite materials starts to reduce, leading to the decrease of compressive strength.
The compressive strength of composite materials reaches optimum at the sepiolite nanofibers proportion of 2%.

One of the best known non-destructive evaluation techniques is the Acoustic Emission Method, which determines the active defects in the tested materials [7].
The rate and characteristics of the signals received are strongly dependent on the damage process and enable the monitoring of fracture, corrosion and healing in cementitious materials [10].

Whereas magnetostrictive effect characterizes the change of the shape of a ferromagnetic material during magnetization, the inverse magnetostrictive effect characterizes the change of material magnetization for given magnetizing field strength when mechanical stress is applied to the material.
Therefore stress plays an important part in the magnetization of ferromagnetic materials such as silicon steel and low-carbon steel.

All of the higher order symmetric and antisymmetric modes have their cut off frequencies, characteristic for different materials.
The reason is that bone unlike engineering materials is a living structure and its properties depend on human factors - age, physical activity, health status, etc.
Its mechanical behavior can be fairly well approximated by the constitutive models developed for engineering materials.
It is imaginable that the methodology established for biological tissues will be transferable on materials like metal foams where visual inspection is impossible.
