Video Summary

Module five of the ESCSI series on internal curing highlights how this method enhances concrete sustainability. The focus is twofold: extending concrete service life and reducing carbon footprint. Internal curing reduces corrosion in reinforced concrete by hydrating more cement and reducing porosity, which diminishes chloride ion transport, delaying corrosion. It also minimizes shrinkage cracks, preventing chloride ions from reaching reinforcing bars. Studies show that switching to internally cured, high-performance concrete can extend service life significantly compared to conventional mixes.<br /><br />Additionally, internal curing facilitates the use of supplementary materials like fly ash, reducing cement and clinker usage, thereby lowering CO2 emissions related to cement production. By adjusting water-to-cement ratios and leveraging internal curing, concrete formulas can maintain strength, reduce autogenous shrinkage, and lower fluid transport. This comprehensive approach makes concrete designs more sustainable by utilizing materials more efficiently, improving durability, and reducing environmental impact.
