Geopolitical Vulnerability and Structural Concentration in Iraq’s Oil Export System A Statistical and Market-Based Analysis under Regional Conflict Conditions
This study investigates the structural characteristics and temporal variability of Iraq’s crude oil export system during the first quarter of 2025, with particular emphasis on its exposure to geopolitical disruptions. Using descriptive statistical analysis and graphical modeling, the study identifies patterns of fluctuation, concentration, and dependency within export flows. The results indicate that total crude …
Incorporation of Waste EPS in Mortar for Lightweight and Energy-Efficient Construction
This study evaluates the performance of lightweight mortar incorporating recycled expanded polystyrene (EPS) as a partial replacement for natural river sand. Targeting non-structural applications plastering, rendering, and masonry bedding a 25% volumetric sand replacement was investigated. The water-to-cement ratio was maintained between 0.45 and 0.50 using an OPC:sand ratio of 1:3 by volume. Results show …

Performance of Concrete Incorporating Boat Fiber Waste Powder as a Partial Replacement for Fine Aggregates
This study investigates the feasibility of using Boat Fiber Waste Powder (BFWP) as a partial replacement for fine aggregates in M30-grade concrete. BFWP, derived from discarded glass-fiber-reinforced polymer (GFRP) boat components, was incorporated at 0%, 10%, 20%, 30%, and 40% replacement levels by mass of fine aggregate. Workability (slump test, ASTM C143), 7-day and 28-day …
Effect of Coal Bottom Ash on the Plasticity and Swelling Behavior of Expansive Clayey Soil
Expansive clayey soils present persistent engineering challenges due to their high plasticity and pronounced swelling behavior upon moisture fluctuation. Conventional stabilization methods such as lime and cement treatment are effective but entail substantial economic and environmental costs. This study investigates the viability of coal-derived bottom ash (BA), sourced from the Norochcholai Coal Power Plant in …
