ULTRA HIGH-PERFORMANCE CONCRETE BEHAVIORAL STUDY
Journal of critical reviews, 2022 It is investigated in the study paper how UHPC reacts when used as a bridge girder material. The early-age shrinkage, transfer length, creep behavior, and shrinkage following steam treatment of four optimized girders were all investigated. Data was gathered using vibrating wire gauges at strategic locations inside each girder after re casting.

Advanced Functional Materials, EarlyView.From a database of 170 pentagonal 2D materials, 4 candidates exhibiting altermagnetic ordering are screened. Furthermore, the spin‐splitting and unconventional boundary states in the pentagonal 2D altermagnetic monolayer MnS2 are investigated. A MnS2‐based altermagnetic tunneling junction is designed and, through ab initio quantum transport simulations,
