Structural Lightweight Concrete Containing Recycled Lightweight Concrete Aggregate

KSCE Journal of Civil Engineering, 2018
In this paper, Structural Lightweight Concrete (SLC) containing Recycled Lightweight Aggregate (RLA) is described. Damaged lightweight concrete was used as RLA by crushing it into fine particles, and used to replace fine limestone aggregate of up to 45% by weight.
