Interface Bonding Strength of Composite White Cast Iron Embedded Steel Bar

The interface bonding strength of composite white cast iron embedded reinforcement steel bar was researched. The experimental results show that the interface bonding strength of this kind composite white cast iron is effected by surface treatments of steel bar and factors of cast-in process such as the volume ration of liquid white cast iron to the steel bar which inserted in, pouring temperature, preheated temperaature of steel bar.
