What is Reducing Concrete Shrinkage with LWA about?

This study evaluates the use of prewetted, vacuum-saturated lightweight aggregate (LWA) as an internal curing agent to reduce concrete shrinkage, particularly in bridge decks. Results indicate that replacing normalweight aggregate with PVS LWA leads to decreased shrinkage over time, with extended curing periods further enhancing this effect. The findings suggest a combined strategy of using PVS LWA and slag cement to effectively minimize drying shrinkage and improve the durability of concrete structures.
