The influence of casting position and depth of concrete pour on bond strength

Structural Concrete, Volume 26, Issue 6, Page 7240-7255, December 2025.
Abstract Bond strength of steel bars cast near the top of a concrete pour may be lower than that of bars cast close to the bottom due to an increase in water content, to consolidation of fluid concrete below the bar, or to both. Current design codes typically require increases of 20%–40% in anchorage and lap lengths in “poor” bond conditions to allow ...

Mechanical and electrical properties of magnetically aligned micro steel fiber‐reinforced self‐compacting concrete

Structural Concrete, Volume 26, Issue 6, Page 7653-7677, December 2025.
Abstract This study investigates the impact of magnetic alignment of micro steel fibers (0.35%, 0.70%, and 1.05% contents) on the mechanical and electrical properties of fiber‐reinforced self‐compacting concrete. A simplified magnetic circuit was designed and built to align the fibers within the concrete matrix.

Experiments and performances of strain-hardening fiber low cementitious composites

Advances in Mechanical Engineering, 2015
The ordinary Portland cement is a main binding material in normal concrete or high-performance fiber cementitious composites. However, the carbon dioxide (CO 2 ) emission during the ordinary Portland cement manufacturing process is up to about 7.0% of ...
