RC column strengthening by lateral pre-tensioning of FRP [PDF]

, 2003
This paper presents a unique strengthening technique for existing concrete columns that use expansive materials to apply lateral pre-tensioning. The technique increases the capacity and ductility of a column as well as achieving better utilisation of the

Prefabricated Ferrocement Jacket for Repairing and Strengthening Axially Loaded Square Sub-Standard Concrete Stub Columns

Buildings, 2023
For decades, ferrocement has been used to repair, strengthen, and even build structural components because it is a long-lasting and reasonably priced material. However, onsite ferrocement jacketing is time-consuming and labour-intensive.

The Effect of Incorporating Graphene Nanoplatelets in the Engineering of Cementitious Composites on Compressive and Tensile Strengths for Potential Applications as a Repair Material

Engineering Proceedings, 2023
Repair methods have been adopted to restore the integrity of structures and ensure their safety and longevity. Although jacketing is commonly adopted as a repair method, its implementation results in added loads and a reduction in dimensions and free ...
