Raw materials and equipment The raw materials of dynamic experiments in lab are mainly industrial pure iron, 75 ferrosilicon and boron oxide, and the asistant material are the lime, magnesia and fluorite, etc.
The chemical components of all kinds of materials were shown in Table 1 and Table 2.
The raw materials and reaction things were measured with X-ray diffraction device.
For boron oxide reducing areaction, the existing materials containing silicon mainly are Si, SiB6 and CaSiO3 in slag [8~9], and other materials containing silicon are very few.

There are many factors affecting concrete resistivity, such as compositions of raw materials, mix proportions and service condition, etc; but the most direct and effective method is adjusting the compositions of raw materials.
Materials and experimental set-up In this experiment, ordinary Portland cement (OPC), fly ash (FA classⅡ), slag (SL), aggregates (sand 0-5 mm, coarse 5-25 mm) and naphthalene super-plasticizer (NS) were used as concrete materials.
Fig.4 The effect of two mixed ratio on concrete resistivity Fig.5 The effect of two mixed content on concrete resistivity Discussions The materials based on cement, such as cement mortar and concrete, are nearly all ionic conductor materials, the current carrier during electric current transporting in concrete is ion [11], so the compaction rate and ionic concentration are the main influencing reasons for the resisitivity of such materials.
