This paper investigates effects of lateral restraint and inclusion of polypropylene (PP) and steel fibers on pore pressure, thermal stress, and explosive spalling in ultra-high-performance concrete (UHPC) at high temperature. Temperature and pore pressure were measured simultaneously at different de...
