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.

Analysis of Temperature and Displacement Fields in the Freeze Construction of Overlapping Cross‐Passages Within Water‐Rich Sand Layers

Geofluids, Volume 2026, Issue 1, 2026.
In the construction of an F‐type cross‐passage in an overlapping‐type shield tunnel using the artificial ground freezing method, the development of the distal frozen wall is difficult to control, and ground deformation is influenced by the superimposed disturbance of successive construction steps. Existing studies are insufficient to fully characterize

Effect of Curing Temperature on Microstructure and Durability of Concrete: A Review

Journal of Engineering, Volume 2026, Issue 1, 2026.
The microstructure and durability of concrete are greatly influenced by the curing temperature. High‐temperature curing accelerates cement hydration; however, it may lead to uneven distribution of hydration products and increased porosity. In contrast, low‐temperature curing retards hydration, resulting in an insufficient hydration formation products ...

Optimizing the construction process: State‐of‐art, innovations, and potential benefits of temperature match curing

Structural Concrete, Volume 26, Issue 6, Page 7312-7325, December 2025.
Abstract The temperature match curing (TMC) method significantly enhances the accuracy of concrete property assessments by replicating in situ curing conditions in test specimens. While this method has remained underutilized and relatively unknown in the industry due to its complexity, the advent of Internet of Things and wireless sensor technologies ...
