ASTM International develops concrete test standard
The proposed standard will be for fibre-reinforced concrete (FRC) and ultra-high-performance concrete (UHPC) under stress.
The WK73384 standard should help determine whether an FRC or UHPC mixture meets the required quality for its intended structural performance.
The standard is intended to be a a practical tool for quality control, product qualification and specification compliance. It is designed for government agencies, including Departments of Transportation, fibre manufacturers, FRC/UHPC suppliers, research and commercial laboratories, and regulatory bodies.
'Tensile properties are especially important in FRC and UHPC because they directly affect how structural elements made from these materials behave and ultimately fail,' says Chao, at the University of Texas at Arlington, USA. 'To ensure consistent quality in FRC/UHPC mixes, it's important to measure these properties reliably.'
ASTM says this effort directly relates to the United Nations Sustainable Development Goal #9 on industry, innovation and infrastructure and Goal #11 on sustainable cities and communities.
