“…It was observed that due to the PVA fiber bridging, the toughness of the concrete materials was significantly increased under dynamic compression. Based on tests conducted on SFRC, Rong et al (2010) reported significant improvement in its toughness with increase in the fiber percentage as well as the strain rate however no appreciable change was observed in DIF (strength). Wang et al (2011) reported the bridging effect of fibers in the failure of SFRC.…”

This paper investigates the stress-strain characteristics of Hybrid fiber reinforced concrete (HFRC) composites under dynamic compression using Split Hopkinson Pressure Bar (SHPB) for strain rates in the range of 25 to 125 s -1 . Three types of fibers -hooked ended steel fibers, monofilament crimped polypropylene fibers and staple Kevlar fibers were used in the production of HFRC composites. The influence of different fibers in HFRC composites on the failure mode, dynamic increase factor (DIF) of strength, toughness and strain are also studied. Degree of fragmentation of HFRC composite specimens increases with increase in the strain rate. Although the use of high percentage of steel fibers leads to the best performance but among the hybrid fiber combinations studied, HFRC composites with relatively higher percentage of steel fibers and smaller percentage of polypropylene and Kevlar fibers seem to reflect the equally good synergistic effects of fibers under dynamic compression. A rate dependent analytical model is proposed for predicting complete stress-strain curves of HFRC composites. The model is based on a comprehensive fiber reinforcing index and complements well with the experimental results.

“…For example, Millard [10], Mao [11], Wu [12], and Yi [31] investigated the blastresistance characteristics of UHPFRC. Rong [13,14], Bragov [15], Caverzan [32], Tran [33] and Wang [34] presented the mechanical properties of UHPFRC under high strain rate loading. Nevertheless, all these studies did not consider the cost of utilized fibres, which is significant, since the cost of 1% volume content of fibre applied in UHPFRC is generally higher than that of the matrix [35].…”

“…For example, Li and Xu (2009) concrete based on a SHPB system; Rong et al (2010) investigated the dynamic compression behavior of ultra-high performance cement based composites; Wang et al (2008) obtained the stressstrain relationship of steel fiber-reinforced concrete under dynamic compression based on SHPB. For RAC, Chakradhara Rao et al (2011) have studied its behavior under low velocity drop weight impact load.…”

This paper presents the experimental results of recycled aggregate concrete (RAC) specimens prepared with five different amount of recycled coarse aggregate (RCA) [i.e. 0, 25%, 50%, 75% and 100%] subjected to compressive loading based on split Hopkinson pressure bar tests. Strain-rate effects on dynamic compressive strength and critical strain of recycled aggregate concrete were studied. Results show that impact properties of recycled aggregate concrete exhibit strong strain-rate dependency, and increase approximately linearly with strain-rate. The transition point from low strain-rate sensitivity to high sensitivity decreases with the increase of matrix strength.
