Alkali-resistant bacteria are capable of repairing cracks in concrete, which could enhance the reliability of underground nuclear waste storage facilities. Experiments have shown that the effectiveness of this "self-healing" process depends on the presence of organic matter, and the technology requires further research before it can be put into practical use.
Scientists have developed an eco-friendly material for 3D-printed houses that reaches construction-grade strength in just three days, compared to the usual 28 days required for conventional concrete. This innovation speeds up building processes and reduces CO₂ emissions.
Scientists at PSI have developed an artificial intelligence system that accelerates the search for new low-carbon cement formulations while maintaining their strength. This approach could significantly reduce CO2 emissions in the industry.
