Abstract: This paper examines the rate dependence in engineered cementitious composite (ECC), a promising material for seismic, impact-, and blast-applications. Research focus has been placed on uncovering the source of rate dependence in ECC and composite re-engineering. Test results show a strong decrease in tensile strain capacity with increasing strain rate in particular versions of ECC. Single fiber pullout test reveals that change in the interface chemical bond with rate is responsible for the loss of composite tensile ductility. Preliminary results in composite re-engineering confirm that extreme ductility of ECC can be retained under seismic loading rate.
