Weak subbase soils pose a significant challenge in road construction, particularly in tropical regions where expansive and low-bearing-capacity soils are prevalent. Conventional stabilizers such as cement and lime, while effective, are associated with high cost and substantial carbon emissions. This study investigates the combined effect of rice husk ash (RHA) and waste putty dust (WPD) …

Assessing the Effectiveness of Rice Husk Ash and Putty Waste Dust as Sustainable Additives to Enhance the Performance of Subbase Materials in Road ConstructionRead More

The construction sector is responsible for a significant share of global CO₂ emissions, primarily from Portland cement production. Rice husk ash (RHA), an agro-industrial by-product rich in amorphous silica, offers a promising pozzolanic substitute for cement. This study evaluates the mechanical and durability performance of solid masonry blocks (215 mm × 105 mm × 65 …

Global electronic waste generation is accelerating at 3% to 4% annually with forecasts indicating volumes near 55 million tons per year by 2025. Managing e-waste disposal grants substantial challenges due to harmful constituents and storage restrictions. This investigation assesses electronic waste capability as a coarse aggregate substitute in M25 grade concrete. Testing was conducted on …

Evaluating E-Waste as a Partial Coarse Aggregate Substitute in M25 Concrete- A Sustainability PerspectiveRead More

Mortar joint thickness significantly influences the mechanical behavior of masonry structures, yet its quantitative effects remain inadequately characterized. This study investigates the impact of three mortar joint thicknesses (10 mm, 20 mm, and 30 mm) on the compressive and shear strength of clay brick walls through comprehensive experimental testing. Eighteen wall specimens were constructed using …

Effect of Mortar Joint Thickness on the Mechanical Properties of Clay Brick Masonry WallsRead More

This paper examines the potential of Building Information Modeling (BIM) to enhance economic sustainability in Sri Lanka’s residential construction sector by building upon an existing dissertation and relevant literature. A mixed-methods approach comprising a structured questionnaire administered to 25 industry professionals and in-depth interviews with three experts (a civil engineer, a structural design engineer, and …
