Sustainable Cementitious Composites from Industrial Waste and Supplementary Materials
This community develops concrete, mortar, and cementitious binders by incorporating industrial by-products like fly ash and slag, alongside novel additives such as graphene oxide, to enhance mechanical strength and durability while reducing the environmental footprint of construction materials.
The research focuses heavily on formulating geopolymer concrete and alkali-activated slag, utilizing supplementary cementitious materials such as fly ash, blast furnace slag, and silica fume to replace traditional portland cement. Key performance metrics include compressive strength, chloride ion resistance, and pore structure optimization. A significant strand of work involves stabilizing municipal solid waste and waste incineration fly ash within these matrices, addressing heavy metal leaching and long-term durability. The community also investigates fiber-reinforced composites and the microstructural effects of hydration, often employing machine learning to predict material properties based on chemical composition.
The largest share of the community's output is found in calcium research, accounting for 3.8% of all calcium research, with 12,098 papers. This is followed by carbon, where the community represents 0.9% of research with 8,326 papers, and chlorine, contributing 2.2% of chlorine research with 5,418 papers.
The community comprises 46,740 papers, publishing most frequently in Construction and Building Materials, Cement and Concrete Research, and Journal of Building Engineering.
Recent work continues to explore the synergistic effects of recycled powders and nano-modifications on mechanical properties, as well as the use of machine learning to predict chloride resistance and the stabilization of dredged sediments using low-carbon supersulfated cement.
