Development of High Strength High Ductility Concrete

Abstract

The development of a new material, High Strength High Ductility Concrete (HSHDC), and its unique composite properties are reported in this paper. HSHDC attains an average compressive strength of 160 MPa (23 ksi) and average tensile strain capacity of 3.5%. The micromechanics-based design approach, which guided the development of HSHDC, is highlighted. A comparison of the specific energy absorption under direct tension of HSHDC with other concretes of this class is also presented.
