Flexural behavior and cracking of lightweight RC beams containing coarse and fine slag aggregates

This study contributes to investigating the potential of using lightweight slag aggregates (SL) in structural applications, as well as exploring the near-optimal options of using fine and/or coarse SL to construct high-performance lightweight structural elements. Large-scale self-consolidating reinforced concrete beams were cast with different combinations of lightweight SL and conventional aggregates. All beams were tested under four-point …
