Mechanical performance and impermeability of self-healing concrete for deep mine shaft linings under hydro-mechanical coupling

Zongchuang Ding, Zhishu Yao, Xiaohu Liu, Xianwen Huang et autres

ABSTRACT Concrete structures exposed to severe environments are susceptible to cracking, which accelerates water penetration and durability degradation. Although self-healing technologies have attracted considerable attention, the simultaneous improvement of mechanical recovery and impermeability remains challenging, especially for high-performance concrete applications. In this …

Damage evolution mechanism of CA-UHPC in deep frozen shafts under hydro-mechanical coupling based on AE technology

Siyuan Shu, Zhishu Yao

Deep frozen shaft linings are subjected to a high risk of failure due to the coupled effects of elevated in-situ stress and hydraulic pressure. However, the damage evolution behavior of Coarse Aggregate Ultra-High-Performance Concrete (CA-UHPC), a promising high-performance lining material, under hydro-mechanical …

Mechanical Properties and Constitutive Relationship of Cretaceous Frozen Sandstone under Low Temperature

Siyuan Shu, Zhishu Yao, Yongjie Xu, Chen Wang et autres

During the construction of coal mine shafts through Cretaceous water-rich stratum using the freezing method, the frozen shaft lining can break and lose stability. Hence, it is necessary to examine the mechanical properties and constitutive relationship of Cretaceous water-rich sandstone under the …
