Temperature‐dependent shear behavior and constitutive model of the rock–concrete interface

Deep Underground Science and Engineering, Volume 5, Issue 2, Page 350-366, June 2026.
Shear tests were conducted to investigate the temperature‐dependent shear behavior of the rock–concrete interface, highlighting the interaction between the surrounding rock and the lining during tunnel fires. Under experimental conditions, concrete exhibited greater temperature sensitivity than rock, with the shear fracture surface transitioning from ...

Effect of expansive agent and internal curing agent on crack resistance of C50 silica fume wet-mix shotcrete

Advances in Mechanical Engineering, 2019
High-strength shotcrete is always needed to strengthen rock support. However, it will reversely increase the crack risk. Crack normally goes against the durability and shortens the service life of shotcrete.

Review of Research on Reinforced Concrete Shell Structure Produced Using an Inflated Form

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Reinforced concrete shell structures produced using an inflated form are widely used in large‐span thin‐shell spatial structures. Unlike the construction technology of traditional concrete building structures, this method involves prefabricating the membrane material into a designed shape as the construction framework.
