Comparative Analysis of Concrete Mix Designs Considering Aggregate Shape on Workability & Compressive Strength
Aggregate shape is an important factor for concrete performance, but most existing studies have focused on idealized single-shape aggregate rather than mixed-shape aggregate compositions that are common in practice. The present work is an experimental investigation on the influence of coarse aggregate shape composition, individual and systematic blends on workability and compressive strength of M25 …
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 …

Mechanical and Physical Properties of Heat-Treated Crumb Rubber Concrete at High Fine Aggregate Replacement Levels Implications for Sustainable Lightweight Construction
The escalating global production of waste tires exceeding 1.5 billion units annually presents an acute environmental challenge that demands integration with sustainable construction strategies. This study investigates the mechanical and physical performance of concrete incorporating heat-treated crumb rubber (CR) as a partial fine aggregate replacement at six substitution levels: 20%, 30%, 40%, 50%, 60%, and …
