Building and infrastructure damages, such as tunnels, have become a more important issue
because of the continuous expansion of rural and urban constructions. It is well-known that …

Ultra-high performance concrete (UHPC) is a novel concrete class characterized by a
compressive strength of more than 150 MPa. One of the most significant drawbacks of …

This paper investigates the individual and combined effects of polypropylene (PP) fibers,
steel fibers, and aggregate size on spalling behavior and pore pressure build-up of ultra …

Concrete tends to spall explosively under fire due to the combined effect of thermal stress
and pore pressure build-up. For an anti-spalling strategy in the concrete mix design, one can …

Measuring pore pressure build-up in concrete during heating is quite challenging due to a
number of adverse factors that includes lack of instrumentation, test conditions, and …

Radiation is one of the most important problems for nuclear power plants. To fulfill the urgent
need for building materials with high radiation resistance and improved mechanical and …

Lightweight aggregate high-strength concrete (LWA-HSC) exposed to high temperatures
usually exhibits the poor resistance to the deterioration properties of materials, which would …

The influence of a combined curing composed of precuring in hot water and heating in dry
air on mechanical properties and explosive spalling of ultra-high performance concrete …

Experimental investigations are conducted on the explosive spalling behavior of two types of
ultra-high performance concrete (UHPC), ie, UHPC with coarse aggregate (UHPC-CA) and …

Explosive spalling is a major threat to fire safety of reinforced concrete structures. A deep
understanding of pore pressure build-up is important for evaluating and mitigating this …
