Thermal Shock Damage in Construction Materials: Impact and prediction of concrete and natural rocks behavior

Building materials generally perform poorly in a high temperature environment. Residential fires and fires in road tunnels are common occurrences. Furthermore, some factories have no option besides exposing their infrastructure to very high temperatures due to the nature of their operation logistics. Therefore, there is a clear need for...

Experimental investigation on the structural response of RC slabs subjected to combined fire and blast

Reinforced concrete (RC) submerged floating tunnels (SFTs) represent a possible solution for crossing wide, deep fjords, and is considered for the E39 highway route along the Norwegian west coast. With regard to SFTs, the specific accidental scenario that is under investigation is the combined action of fire and subsequent internal explosion,...

Self-healing of Al₂O₃ containing Ti microparticles

This work explores the possibility of using embedded micron-sized Ti particles to heal surface cracks in alumina and to unravel the evolution of the crack filling process in case of pure solid-state oxidation reactions. The oxidation kinetics of the Ti particles is studied and the results are applied in a simple model for crack-gap filling....
