Faculty Civil Engineering and Geosciences Department Structural Engineering Date 2014-12-31 Abstract The synergistic action of a cementitious matrix and fibres can result in strain hardening in tension. The accompanied tensile strain capacity can be an important design parameter for strain-hardening cementitious composites in order to prevent the localization in a single crack and to assure that the stress is at least the tensile strength o f the unreinforced matrix. Such a behaviour is desired for example for bridge decks or joints where the strain-hardening material has to follow the deformations of either the substructure or that of the total structure. An experimental study was executed in order to determine the tensile strain capacity of cementitious composites. As a start of the study, a reference mixture developed at the University of Michigan was chosen. Adjusted mixtures in three different compressive strength classes and straight fibres of two different lengths were applied. The six mixtures were tested on characteristics in the fresh and in the hardened state. This paper discusses experimental results and observed failure pattems. The tensile strain capacity was the highest for the lowest compressive strength and with longer PV A-fibres applied.
