ASTM International's concrete and concrete aggregates committee (C09) is developing a proposed standard (WK73384) that will evaluate the tensile performance of fiber-reinforced concrete using cylindrical specimens with double-punch loading. The proposed standard contains "pre- and post-peak tensile properties (that) hold great significance in fiber-reinforced concrete (FRC) and ultra-high-performance concrete (UHPC). These properties serve as the fundamental characteristics of FRC and UHPC, playing a vital role in determining the capacities and failure modes of structural members constructed from these materials," says, Shih-Ho Chao, ASTM International member and professor of civil engineering at the University of Texas at Arlington. He says that FRC and UHPC provide enhanced durability over conventional concrete, which "has the potential to encourage the adoption of these durable materials, thereby promoting sustainable development within society, particularly in terms of sustainable infrastructure." |
