Spall Strength of Steel Fiber Reinforced Concretes
The spall fracture of steel fiber reinforced concretes (SFRC) is investigated with the strain wave profiles in buffer bar behind the specimen bar in a large size Hopkinson pressure bar equipment. The experimental results indicate that the spall strength of SFRC is related to the steel fiber volume ratio, the compressive strength of concretes and the load rate (impact velocity). The spall strength of SFRC empirical formula shows the relationship between these factors. The conclusion that the steel fiber has the effect to improve the ability to prevent spall fracture is of real importance in the correlative numerical simulation and protective engineering design.
