“…The bridging of cracks and subsequent deformation hardening leads to the formation of multiple cracks with typical crack size ranging from 60 -200 µm prior to localization of deformations [1,3]. The crack width control provided by ECC is desirable from structural and durability viewpoints as it minimizes ingress of water and contained substances which can lead to depassivation and corrosion initiation of steel reinforcement [4,5].…”

This paper describes an experimental investigation of the shear behavior of beams consisting of steel Reinforced Engineered Cementitious Composites (R/ECC). This study investigates and quantifies the effect of ECC's strain hardening and multiple cracking behavior on the shear capacity of beams loaded in shear. The experimental program consists of R/ECC beams with short (8 mm) randomly distributed Polyvinyl Alcohol (PVA) fiber and conventional Reinforced Concrete (R/C) counterparts for comparison with varying shear reinforcement arrangements. Beams were loaded until failure while a Digital Image Correlation (DIC) measurement technique was used to measure surface displacements and crack formation. The shear crack mechanisms of R/ECC are described in detail based on findings of DIC measurements and can be characterized by an opening and sliding of the cracks. Multiple micro-cracks developed in a diagonal arrangement between the load and support points due to the strain-hardening response of ECC in tension. The strain-hardening response strongly influenced the shear response of the beam specimen.

“…For HPFRCC after cracking, one of the advantages of HPFRCC is the formation of fine cracks. Some research on the effect of fine cracks on penetration of substances such as oxygen, water, chloride ions, and carbon dioxide has been done Hiraishi et al 2005). Further, multiple cracking with fine cracks imparts corrosion mechanism changes to the rebars within the HPFRCC .…”

High Performance Fiber Reinforced Cement Composites (HPFRCC) show multiple cracking and strain-hardening behaviors in tension. Current applications in Japan include bridge decks, building dampers, retaining wall, irrigation channels and so forth. While the novel properties of HPFRCC are well known, the required performance and its criteria have not been clarified. For example, in addition to tensile load bearing capacity, protection against penetration of substance through fine cracks is also important. Clarification of the required performance and its criteria for HPFRCC is important to evaluate the design concepts of each application. This paper introduces recent applications using HPFRCC in Japan, focusing on required performance.
