Alternative Waste Characterization and Its Functional Reuse in Cement-Based Composites
Researchers found that during COVID-19, people threw away more face masks and consumed more tea, so they tested mixing these waste materials into cement to make building materials. Adding small amounts of masks and tea waste to cement can help reduce waste while still making strong enough construction materials. This approach could help solve the growing problem of pandemic-related waste while creating useful building supplies.
