Alternative Cementitious Binders from Industrial Waste and Phosphate Chemistry
This community develops cement and concrete alternatives by substituting traditional Portland cement with industrial by-products like fly ash and slag, or by using phosphate and oxychloride chemistry, aiming to reduce carbon emissions and utilize waste streams.
The research focuses on formulating binders from fly ash, blast furnace slag, and alkali-activated slag, alongside magnesium phosphate and oxychloride cements. Key materials include calcium sulfoaluminate, iron ore tailings, and aluminum dross. The work examines hydration mechanisms, microstructure, and mechanical properties such as compressive strength and chloride resistance. A significant portion of the literature addresses the stabilization of solid waste and the development of low-carbon concrete composites, often incorporating graphene oxide or other nanomaterials to enhance performance.
The community represents the largest share of tracked research for calcium (9.0%), magnesium (5.6%), and chlorine (4.3%). Calcium also contributes the highest number of papers to this group, with 3,182 entries.
The community comprises 14,726 papers, primarily published in Construction and Building Materials, Cement and Concrete Research, and Cement and Concrete Composites.
Recent work explores the synergistic effects of magnesium slag in alkali-activated systems, the use of carbonated recycled powders in low-carbon binders, and the dispersion of carbon nanomaterials in cementitious composites.
