Development of Optimally Reinforced Glass/Bamboo Fiber and Rice Husk/Bagasse Filler Agrostone Composite Panels for Interior Panel Applications

Journal of Engineering, Volume 2026, Issue 1, 2026.
Agrostone panels, popularly used for interior walls in construction, are usually made from sustainable agricultural waste such as bagasse as filler and glass fiber as reinforcement in a binder of pumice, MgO, and MgCl2 solutions. The present work has gone ahead of one step by adding rice husk and bamboo fiber, which are abundantly available in Ethiopia,

Stone‐Cutting Dust as a Sustainable Supplementary Cementitious Material: A Comprehensive Review of Its Physicochemical and Mechanical Effects

Journal of Chemistry, Volume 2026, Issue 1, 2026.
Ordinary Portland cement (OPC) remains the most common binder used in construction and accounts for nearly 7%‐8% of the world’s CO2 emissions due to calcination of limestone and high energy use during clinker production. Reducing OPC content using SCMs is one of the major strategies to achieve sustainable construction.

Investigation of the Natural Pozzolans for Usage in Cement Industry

Procedia Technology, 2015
AbstractOne of the most important aspect of selecting the proper natural pozzolanic material as admixture of Portland cement in concrete or mortars is the chemical reactivity and mineralogical content. If the chemical reactivity index and quartz content are high the pozzolans can substitute the cement from the binder groundmass in a greater proportion.
