Abstract
This paper describes an investigation of standardized test methods to characterize fiber
reinforced cementitious composites in terms of their behavior under flexural loading and its
relation to their tensile stress-deformation response. Flexural testing and derivation of the
tensile stress-deformation response are preferred in standardized testing of Fiber Reinforced
Cement Composites (FRCC) over the direct assessment of the tensile behavior because of the
more convenient test setup and ease of specimen preparation. Four-point bending tests were
carried out to evaluate the flexural response of FRCC and their results are compared to data
obtained from direct tensile testing. The details of the formation of cracking are an important
underlying assumption in the standardized evaluation procedures as well as in the established
correlation models between flexural and tensile behavior. This detail has been documented in
the present study using a photogrammetric image analysis system, which can be used to relate
the flexural crack formation and resulting load-deformation response to the data obtained
from direct assessment of the tensile stress-crack opening response of FRCC materials.
