Introduction In recent years, magnesium and its alloys have attracted much attention as potential biodegradable bone implant materials due to their biocompatibility, biodegradability and mechanical properties analogous to natural bones [1, 2].
However, limitations such as alkalization, hydrogen release, high concentration of magnesium ions and decrease in mechanical properties of implant materials [3-5], caused by high corrosion rate in body's fluid, had prevented their further clinical use.

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.

As scaffolds, biodegradable polymers offer a number of advantages over other materials.
It can be used for different types of samples such as thermoplastic, elastic, or fibrous materials that cannot yet be ground as efficiently as brittle materials [23].
