Toward Zero Waste Mining: Circular Economy of Copper Slags
Mining and metal extraction processes generate over 90% of global waste. With the rapid increase in population and urbanization, the demand for geotechnical applications and construction materials constantly increases and can absorb the entire quantity of slags generated.

Bio-Based Renewable Additives for Anti-Icing Applications (Phase II) [PDF]
The performance and impacts of several agro-based anti-icers along with a traditional chloride-based anti-icer (salt brine) were evaluated. A statistical design of experiments (central composite design) was employed for developing anti-icing liquids ...

Rheological Evaluation of Asphalt Cements Modified with ASA Polymer and Al2O3 Nanoparticles
AbstractThis study aims to evaluate and characterize the properties of modified asphalt cements exposed to high temperature. The Acrylate Styrene Acrylonhrtilrei (ASA) polymer and nano aluminum oxide (Al2O3) nanoparticles were added to the base asphalt cement with concentrations of 3, 5 and 7% of the weight of asphalt. The storage stability, viscosity,

Assessing the rheological properties of bio modified asphalt cement
The production of asphalt cement binder in Iraq is conducted through the distillation of crude oil. The byproduct of such distillation is the asphalt cement which does not practice any further processing further processing of the binder is considered vital to control its physical properties and chemical composition.
