Effect of moderate temperatures on compressive strength of ultra-high-performance concrete: A microstructural analysis

Concrete with two types of steel fibres and a polypropylene fibre prevented spalling and preserved the compressive strength at 300 °C, which makes these concretes suitable for long-term applications up to 300 °C, such as for steam collectors or thermal energy storage systems. The compressive strengt...
