Latest Patents
Yifei Yan's latest patents include groundbreaking advancements in the field of eco-friendly concrete. His first patent details a formulation for fire-resistant eco concrete blocks containing waste glass. This innovation incorporates a cementitious binder of alumina cement, along with recycled fine and coarse aggregates. Notably, the inclusion of 10-50 wt % recycled particulate glass cullet of 600 microns or less enhances the block's thermal conductivity characteristics under elevated temperatures, achieving at least three hours of fire resistance, a density below 2000 kg/m³, and a compressive strength of at least 7 MPa.
The second patent focuses on synthetic aggregates fabricated from more than 70 wt % waste materials, which include granulated ground blast furnace slag, waste concrete fines, and sewage sludge ash. These materials are combined with a hydraulic cementitious binder and undergo a unique hydraulic reaction and carbonation in a CO2-rich atmosphere at temperatures below 100°C. The synthetic aggregate produced demonstrates a crush strength exceeding 0.5 MPa after the hardening process, offering a promising alternative to traditional aggregates in construction.
