Low-Carbon Binders and Waste-Derived Cementitious Materials
This community develops alternative cementitious binders and concrete composites that utilize industrial by-products and waste streams to reduce the carbon footprint of construction materials.
The work centers on formulating binders from fly ash, steel slag, furnace slag, and ore tailings, often through alkali-activation or geopolymerization. Key chemical systems include calcium sulfoaluminate, magnesium phosphate, and magnesium oxychloride cements, alongside traditional Portland cement modifications. A significant strand of research focuses on microbially induced carbonate precipitation and the use of graphene oxide or carbon nanomaterials to enhance mechanical properties. The primary objective is to achieve comparable compressive strength and durability while substituting high-emission clinker with lower-carbon precursors and solid waste.
Calcium research is the largest share of the community's output, accounting for 15.8% of all calcium research, with 6,662 papers here. Magnesium and Chlorine follow with 5.2% and 4.7% shares of their respective element research.
The community comprises 21,274 papers, publishing primarily in Construction and Building Materials, Cement and Concrete Research, and Cement and Concrete Composites.
Recent work continues to explore the synergistic effects of alkali-activated slag and fly ash, the stabilization of dredged sediments using low-carbon supersulfated cement, and the dispersion strategies for carbon nanomaterials in cementitious composites.
