On June 1, 2016, Konkuk University announced that A-Hyeon Eom and Su-Ji Ryu, third-year students at the Department of Civil & Environmental System Engineering, published an article titled “Optimal Dimension of Arch-Type Steel Fibre Reinforced Cementitious Composite for Shotcrete” in Composite Structure, which is recorded in the Science Citation Index. Ms. Eom and Ms. Ryu have been part of the Advance Construction Materials & Structures Lab at Konkuk University as "undergraduate researchers” since last summer. The researchers derived an optimal dimension of arch-type steel fibre for cementitious shotcrete based on bond properties with a cement matrix. The bond properties were enhanced by the fibre through frictional resistance force and mechanical anchoring provided by the arch curvature. Given that the improvement of maximum pullout load, initial interfacial toughness, and final interfacial toughness compared to those of hooked-end-types were 171.4%, 153.4%, and 195.8%, respectively, the researchers suggested that the fibre should provide effective bridging action against cracks using a relatively lower volume. “The research project was very interesting because it was the first time I actually recorded data and analyzed the results,” said Ms. Eom. “I gained a deeper interest in my field through the opportunity.” <img style="margin-left: auto; display: block; margin-right: auto;" alt="" src="ArticleFile.do?id=11662989" width="660" height="410" />
