What is Lightweight Sand in Ultra-High-Performance Concrete about?
This study investigates the effects of replacing river sand with pre-saturated lightweight sand (LWS) in ultra-high-performance concrete (UHPC) to enhance mechanical properties and reduce autogenous shrinkage. The findings indicate that a 25% replacement ratio of LWS leads to optimal compressive strength and limited autogenous shrinkage. The use of LWS improves cement hydration and microstructure, demonstrating its effectiveness as an internal curing agent in UHPC.
