Effects of coarse and fine aggregates on long-term mechanical properties of sea sand recycled aggregate

Frontiers of Structural and Civil Engineering 2021, Volume 15, Issue 3,   Pages 754-772 doi: 10.1007/s11709-021-0711-2

Abstract: Typical effects of coarse and fine aggregates on the long-term properties of sea sand recycled aggregaterecycled coarse aggregates).Supportive results show that the compressive strength of SSRAC increase with decreasing recycled coarseaggregate replacement percentage and increasing sea sand chloride ion content.differences between coarse aggregate and cement mortar reduce by adopting sea sand.
