Egypt: Researchers at the University of Cairo have used nanomaterials from agricultural wastes to produce biocement with 'increased strength and durability' compared to ordinary Portland cement (OPC). The study employed microbially induced calcite precipitation (MICP) with the addition of carbon nitride nanosheets and ash from waste maize cobs. Besides its improved physical performance, the researchers also found that their biocement offers improved endurance against water permeability.
