Experimental measurement of double-K fracture parameters of concrete with small-size aggregates

Abstract

The double-K fracture model can well describe the development of cracks undergoing during the entire fracture process in concrete. Therefore, it has been selected as the theoretical basis of the Norm for fracture test of
