The influence of casting position and depth of concrete pour on bond strength
Structural Concrete, EarlyView.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 ...

Recent Advances in Recycling of Copper‐Based Waste Materials: A Critical Review
cMat, Volume 2, Issue 2, June 2025.ABSTRACT Copper plays a crucial role in the civilization of our lives. This review examines the flow of copper from the mining of ores to the end‐of‐life product, with particular emphasis on the recovery and re‐functionalization of copper and copper‐containing wastes. Beginning with the analysis of the global copper market, reserves, supply, and demand,

Global Challenges, Volume 9, Issue 6, June 2025.This study identifies groundwater potential zones in Ethiopia’s Ziway Lake watershed using GIS and the SWAT model. Over half the area shows moderate to very high potential. Nearly 40% of high‐potential zones also have good to excellent water quality. The results offer a practical tool for sustainable groundwater management, with potential application ...
